Green/Multicolor Lines Appear at Certain Zoom Levels

[EliseClaire]

Hello,

My colleagues and I are seeing thin green/multicolor lines appearing in various locations, across different documents, that appear and disappear at various zoom levels. Depending on the document, sometimes it runs along the edge of the canvas, other times it appears outside the canvas (as in the attached test file).

Photoshop version: 24.6.0

Mac OS: 12.6.4

Graphics: AMD Radeon Pro 5500M 8 GB

Screenshot of test file at 40% zoom:

Steps to reproduce:

1. Open test file attached here

2. Zoom to 51% - 63% and the line appears

3. Zoom to <51% or >63% and the line disappears

Thank you!

Doesn't appear here. Maybe your GFX card need updating?

Thank you for taking the time to check the file!

After more testing on different machines, we found this "GPU compositing" checkbox under Preferences > Performance > Advanced Settings. The box was checked for those of us experiencing the glitch. Un-checking the box solved the issue for us!

Not sure yet how or if that will impact performance in any noticeable way, but we're glad to have the lines gone!
