Inaccurate stroke scaling on new objects
When I create a new shape, the stroke scaling is clearly not accurate. I have it set to 1 pixel, however, it appears much, much larger than a stroke set to 1 px.

Strange loops and spikes when using pressure-sensitive brushes with XP-Pen Tablet on Illustrator 29.3 and newer on Windows 11
An employee directed me to this forum to explain my problem (I explained everything here: https://community.adobe.com/questions-652/inconsistent-strokes-when-using-pressure-sensitive-brushes-with-xp-pen-tablet-illustrator-30-2-1-windows-11-1553544)
My system:
Windows 11, Version 25H2 (Windows Ink is deactivated, tried with activated too).
Old tablet: Artist 12 Pro (XP-Pen)
New tablet: XP-Pen Deco Pro MW
I tried all available Illustrator versions (I will explain later).I am getting very weird and inconsistent strokes when drawing with a tablet and the Blob Brush Tool (please see screenshot and video attached EDIT: video too big pls see the article from the other forum, the video is posted there).
I did a ton of troubleshooting…
2 votesHi,
We weren't able to reproduce this issue on our end, so we'd like to gather a few more details to help us investigate further:
1. Wacom/tablet driver version- Could you share the exact driver version you're currently using?
2. Did this issue appear immediately after upgrading to a specific Illustrator version?
3. Illustrator version currently installed?
Regards,
Aishwarya

Dashed strokes with round caps and zero dash lengths (dotted dash) looks very imprecise when using Large Canvas, with GPU Preview
A 1 pt stroke with 0 dash length, when created within a large canvas file, looks chewed. When expanded, the points get baked like this.
CPU Preview shows these correct, but expanding it still creates dancing points.
Doesn’t happening in a normal canvas sized docs.Large canvas should become stable finally. So many bugs with it!

A very thin variable stroke appears shifted
When I reduce the stroke width to a very thin value, the stroke no longer appears center-aligned and instead shifts to one side.

Can't select all and use Outline Stroke directly, especially Clipping Mask items
Can't select all to Outline Stroke directly, some clipping mask items will be missing, then need to adjust one by one, very inconvenient for printing FA

With 'Use Preview Bounds' enabled, resizing an object would instantly jump to geometric bounds, while the bounding box hugs preview bounds
When 'Use Preview Bounds' option is enabled, Illustrator included strokes of the selection into the bounding box.
However, if we try to resize a selection, Ai would make the object suddenly larger, as if the option to respects preview bounds is disabled — take a look at the GIF attached.If we also enable the 'Scale Strokes & Effects' (not shown), we can somewhat understand, why the team chose to do this — if the preview bounds were used to resize with both options enabled, we would get the selection move slightly to respect the scaling of the stroke... but…

Generative Expand ruins stroked linework
Please fix the Generative Expand. It ruins your linework and makes random lines on object. It becomes impossible to work around because even the scissor tool cant cut it since there is a ton of nodes.
It also gets complicated with the shape builder as that tool ruins the stroke weights.
Lastly the stroke / fill thing it keeps swapping it to fill instead of stroke then you have to re put the lineweights every single time.
Some of the parts of the lines even get removed.2 votes -
Sometimes Alt-dragging a Variable Stroke Width width handle results in the other side of the handle snapping to 0
Sometimes Alt-dragging a Variable Stroke Width width handle results in the other side of the handle snapping to 0. Very unexpected behavior.
I have not as yet found a repeatable test case for this, perhaps now that I've posted this bug I will try to isolate it the next time this happens to be and add it here :)

Overprint lines not working in Illustrator 2026 (v. 30)
The overprint feature is not working (both lines and fills). Not only does it not work with the Separation Preview in the app, but when output to PDF it is confirmed to not work. Inks that are indicated to overprint are knocking out.

A width profile that is uneditable and rendered wrong
Take a look at these two path; Illustrator says they have the same width profile, but it’s obviously not correct.
If saved as Graphic styles — these do match.
Paths match.
Directions match (and simple reversing still looks different).
The left-hand path cannot be edited with the native Width tool.I can edit these with Width Selector tool by Astute Graphics, but it makes the width changed in a different spot. Saving the style, clearing the appearance, reapplying the style — heals the bug. Deleting a leftmost segment... this keep the look the same (almost), but the bug gets healed…

Strokes with a profile and have the rounded corners selected end up having pointy corners
The corners of my strokes should have a rounded corner but the moment I adjust the profile with the width tool they turn all pointy

clicking on stroke color in properties box adds fill to stroke
When trying to change stroke color, the properties box shows nothing in the RGB boxes. Clicking in them adds a fill to the stroke which is unwanted. Edit Gradient controls were buggy too

Stroke appears to have Brush applied with no actual Brush
When I am in ANY artboard, I draw a .0139" x .0139" OR 1px x 1px square to center my artboard. I zoom in to as far as I can to then pull my ruler from top left to center the artwork on the page.
2 things,
1 the square (1px x 1px) appears to have a brush stroke on it as it does NOTAND
I cannot pull the centering tool (in ruler, Ctl-R ) onto my artboard to then center the coordinates.
2 votesGPU mode Ai uses by default is fast, but can be imprecise at high zoom levels. To see the art the way it’s drawn, with no precision rounding artifacts, toggle it to CPU mode instead.

線幅を変えると矢印から線がはみ出る
ver26.5（最新）。Windows10使用。
線幅を変えるとパスの終点の矢印から線がはみ出る。
例えば、線幅17に対し、終点を30％などにすると矢印から線の端がはみ出てしまう。
矢印11、12、13、14が該当。
ならないのもありしたが、全部調べていないので、他の矢印もそうなるかもしれません。2 votes

Expanding a bezier path with a stroke larger than the object's radius alters its appearance

As per the title
1) Create a circle
2) Give it a stroke thicker than the radius
3) Expand it2 votes -
The white-filled circle arrowhead has some very strange geometry.
The white-filled circle arrowhead in Support Files/Resources/en_us/Arrowheads.ai has two doubled points in the black circle. This results in unexpected imagery when a path is given this arrowhead, expanded, and has further effects applied.
Screenshots: outline view, and outline view with half of each point pair selected and moved down 1pt.
This was discovered in 25.3.1 but I bet it's been lurking there long enough that it predates your current source control tree. :)

Path+stroke profile weirdness
Plz examine the file. Two paths with different width profiles when reflected. Bottom one behaviour is good, top path behaves badly. Why would this be ?
