Calligraphic Brush, Blob Brush appearance anomalies at small brush sizes (1 pt and above)
Illustrator 22.1, though this is extant in all versions I'm familiar with (since at least CS5).
When drawing with a calligraphic brush (and thus also with the blob brush) at small sizes, certain tight curves result in anomalous shapes extending out from the expected area covered by the brush. The screenshot attached is around 15mm across. AI file also attached. Expected result is that the brushed area corresponds to the shape of the calligraphic brush along the whole length of the path.

Blob Brush changes size after undo operation
Illustrator CC 2017.1.0
I Select blob brush on 2pt.
Draw a bit with it
Hit undo and the blob brush suddenly changes to a much larger size even though it says 2pt in the menu
The only way to get it back is to go to Blob brush menu, select 1pt hit ok, then go back to blob brush menu and select 2pt again.
I expect that when I hit undo the blob brush will stay the correct size
It changes size every time I hit undo

Scatter Brush doesn't align smoothly to curve
Hi, I'm using Illustrator 24.2.3 on an Imac late 2015.
Scatter Brush seems to have issues with curves. If I create a scatter brush from a single object, the line seems to follow the curve loosely in straight line segments, creating a very jagged effect. I've attached images to hopefully clarify. The thinner "smaller brush element" examples I have included are made from a small circle shape a little less than one pixel in diameter. The "jagged" issue seems to disappear, however, if the curve is large enough (see the 11-inch small-brush-circle below) OR until the stroke weight increases to…

Disappearing an outline size diameter of a brush tool
When you just launch the Adobe Illustrator, you can see the outline size diameter of the cursor of brush/blob brush tools, but when you have drawn something the outline disappears , you can see only an icon of the brush and no clue what size is currently on.

Custom art brush results in way too many anchor points when expanded
As reported here by Peachtears13: https://www.reddit.com/r/AdobeIllustrator/comments/1kei4zn/custom_art_brush_results_in_way_too_many_anchor/
Having a simple path (with minimum amount of points), applying a simple art brush (with minimum amount of points), and then expanding it gives a ton of extra points, hardly needed to define resulting shapes.
It worked MUCH better in CS4... and then became much worse in CS6 (or perhaps in CS5) — take a look at the images attached.
Yes, there are tools to deal with the mess afterwards: native Simplify, plugin VectorFirstAid... but it should not be like this in the first place.
And please, do not 'solve' it by throwing in…

Blob Brush strokes often include garbage on turns
What is wrong with Blob Brush. Even with simplest strokes I often get groups, and these have the main part and tiny pieces of garbage next to it in them.
Sometimes these are thinnest slivers, sometimes knotted madness, sometimes chunks chomped off...
If I run simple Pathfinder Add, some of this get 'healed'. Why don’t you do at least this? Why these awfully angular turns and garbled edges happen in the first place? Please study the file.4 votes -
Changing the Transparency removes brush
When I have several lines applied with a Pattern Brush and change the transparency of those lines to 50%, everything is fine. As soon as I return to 100% opacity, the Pattern Brush is completely removed and I have to reapply it.

Stroke Options for Brushes are not sticky
macOS 12.1
Illustrator 26.0.2A brush is applied to an object, then its appearance is modified through the "Options of Selected Object" dialog box found at the bottom of the Brush Panel.
If later the definition of the original brush is changed — all the modifications done through this dialog box are completely wiped out.
I would expect these settings to be sticky.For example, if I flipped a brush across or scaled it for one path and then changed the colorization method for this brush, I would still expect this particular path to be scaled/flipped in the same way.

Blob Brush size is wrong
I select blob or paint brush, pick the size etc, go to use it and it turns to a totally different size and brush. Tried resetting it all, closing the app and reopening, and check to ensure its set to what I want, but it changes to something different everytime

Brushes become a lighter tint of black in an RGB document when expanded or rasterized.
Brushes like Art Brushes are based on a CMYK document. They were created with C0 M0 Y0 K100.
When these brushes are used in an RGB document with an RGB black (0/0/0) for the stroke, the result will be around a lighter 10% black than expected because the CMYK black will be converted to RGB.
You can check that by expanding, rasterizing or Output Preview in Acrobat.
If they had been created in the CMYK document with a 100% Grey instead of CMYK values, they would have converted to the darkest black in an RGB documents (greyscale always keep their…3 votes -
Blending paths with brushes and width profiles works wrong.
Create two lines.
Apply art or pattern brushes to both of them.
Apply width profiles to both of them.
Blend them.
Ai will generate steps that have uniform profiles instead of intermediate.Scatter, calligraphic, and bristle brushes won't let you edit the width profile. I did however test with two calligraphic brush paths with different pressure curves and that was ignored for the intermediary paths. Please test this with bristle and scatter brushes as well.
(this is essentially a reopening of https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/41634754-blending-paths-with-width-profiles-works-wrong with a feature that was missed when originally implementing it, as such I just copied and edited Egor's…

Using Random Size Calligraphic Brush inside of a group/layer with an effect applied makes Ai pick only one size for each brush tip
If a layer or a group has an level effect applied (in this case it’s Transform, for creating symmetric designs), then Ai doesn’t apply random size for the calligraphy brush tips created with Brush tool inside this group/layer — but does it outside of this group / on a normal layer.
Take a look at the test file attached and the GIF recorded.
Clicking with Brush tool randomizes the size for the first object created in Layer 1 (with the effect applied), but each consequential click makes points with same thickness.
But when the same happens on Layer 2, with…2 votes -
Calligraphic brush renders improperly if Roundness is less than 10%
Calligraphic flat brush renders improperly (brush tip is S-shaped) when roundness is less than 10%. Was trying to do calligraphy with 5% flat tip in Illustrator when I noticed this problem, that creates a lot of cleanup. See images.

Stroke weight defaults to 1pt when a new type of brush is applied.
MacOS 12.6.2
Illustrator 27.1.1To replicate the issue:
Assign a 2pt stroke to an object, then apply any brush to it — the stroke weight becomes 1pt.
Switching between brushes of the same type (Calligraphic, Scatter, Art…) seems to keep the weight intact, but switching the type of brush triggers the stroke weight to default back to 1pt.
Expected result: the assigned weight stays the same regardless of the brushes applied.2 votes -
Too many brushes saved in Print.ai (Print.ai = 300 MB) disable Trim View, despite 32 GB RAM
Trim View still worked in a new doc based on my Print.ai, until I opened the brushes tab, then it got disabled.

Pattern Brush 'Hue Shift' does not result in correct appearance of stroke color
This issue is not new and occurs for a few years at least.
I i apply at a pattern brush > Colorization > Method: Hue Shift, the key color does not represent the same color of the choosen stroke color when the brush is applied to a Stroke. The color is always way off. I am well experienced in Illustrator (and certifeid by Adobe) but i can not find any thing i did wrong. That's why i am almost sure this issue is a bug. But please, tell me i am doing something wrong. That way i can help my…2 votesThe solution provided in the comments below.
However, when the key color is automatically gets set as the white (or any grayscale tint) as the most prominent color, the hue shift gets calculated wrong.
If you think Illustrator should pick another color in cases like this — please continue voting.

Holding alt to make the Width tool only change one side of a brushed path snaps the other side to zero.
- Draw a path. Give it a simple, thick stroke.
- Hold down ALT while using the Width tool to change one side's width; note that the other side stays the same width.
- Draw a new path. Give it an art brush or pattern brush.
- Hold down ALT while using the Width tool to change one side's width; note that the other side suddenly snaps to zero-width.
I would swear the Width tool used to behave as in step 2 on brushed paths? It'd be nice to get this reversion fixed. Or to make the Width tool behave consistently across different kind…
