Betas indeed can be quite unstable. I do not offer to work with Beta all the time. After all, these two get installed together and work separately. Disk space might be an issues, SSDs are tiny.
The only reason I think a user should try it is to check if the bugfix indeed solves the problem before it get pushed into the GA build.

Agree with Scott's comment below. After installing Beta, I had to relink many bitmap images in my files. So I got rid of the Beta version. Hoping the new Illustrator (non-Beta) will fix this issue.

Installing a Beta version of a program may fix this one issue, but by installing a beta version you are potentially also inviting in a host of other unforeseen bugs that need will fixing. Not a great recommendation.

I'm still having this issue. Using latest version 28.5 Bitmap TIFFs displaying inconsistently, usually when viewed below 100%

I am experiencing a bug in Illustrator with bitmap images that have a transparent background. When I zoom in or out, strange stripes appear, and I can't see the bitmap correctly. If I toggle the outline view on and off, the issue temporarily resolves, but it returns as soon as I use the zoom function again. I am using a GeForce 4090.

as a title: illustrator displays stripes instead of bitmap images

Thank you for fixing this!! Looks correct in Adobe Illustrator Beta 28.6.0.594.

When this type of image is embedded, if you click on 'Edit In Photoshop', you get an error. Screenshot attached. I know this is a different bug, but it seems possibly related?

Thank you! I really appreciate the bug fix. It will be a big help when working with bitmaps in Illustrator.

I can replicate the issue in Adobe Illustrator 28.5. both on Mac and PC. I hope this is fixed very soon.

Description of the Bug:
Black and white bitmaps are not showing up correctly in GPU mode. When zoomed out, they appear as lines, and in some rare cases, the image appears inverted. Working in CPU preview mode shows the image clearly, but this mode is too clunky, slow, and images are aliased, making it an impractical solution for extended use.

Steps to Reproduce:
• Open Adobe Illustrator.
• Place a high-resolution black and white bitmap (e.g., a 5"x7" 1200 dpi image used in print for line-art or custom halftones).
• Zoom in to 300% or closer, where the image appears fine.
• Zoom out to 150% or further, and the image turns into vertical lines.
• Display bug zoom values depend on the resolution of your image.

Expected vs. Actual Behavior:
Expected: When zooming out to 150% or further, the image should continue displaying correctly.
Actual: The image shows up as lines when zoomed out to 150% or further.

Environment Details:
• System: Intel PC 10850k, 32GB ram, Nvidia RTX 3090 graphics
• Operating System: Windows 11
• Adobe Illustrator Version: 28.5 (tested issue also in 28.4.1 where the issue is non-existent)

Screenshots or Videos:
1. Screenshot showing lines display bug at 263.9% zoom.
2. Screenshot showing lines display bug at 300% zoom.
3. Screenshot showing image displaying correctly at 400% zoom.
4. Video demonstrating the issue.
5. Testing with a line art 9x12 inch 1200dpi sample, problem persists.

Impact on Work:
Not being able to see images correctly when zoomed out is very distracting, slowing down my work, and significantly impacting productivity. The new features in version 28.5, such as link sorting and relinking missing files automatically, are nice, but it is far more important to see images correctly when zoomed out. Due to this bug, I will continue working in version 28.4.1 until it is resolved.

Please revert so GPU works as before. CPU is a slowdown with multiple tiffs on a page.
