Minor editor tab header flickering problem on nVidia graphics adaptors #560

Open DexterLagan opened 2 years ago

DexterLagan commented 2 years ago

DrRacket 8.5 release. Windows 11 x64, GeForce 3070 (Asus Zephyrus M16). On this system, editor tabs flicker badly when moving the mouse over them. On another system with an Intel adapter, no such problem.

I came here to report this same issue. It didn't exist on the previous version of Racket I had installed, which was Racket 8.3. Although, I probably wouldn't describe it as minor, as it is fairly distracting.

I have attached a video of the flickering.

This likely a duplicate of https://github.com/racket/gui/issues/273 and was already fixed in the snapshot builds, will be released as part of 8.6.

I have now tested this issue with Racket 8.6 on Windows 11 (same information as in my comment above), and it looks to be fixed. (Also fixed according to the linked issue.) Below is a video with Racket 8.6.

There is still some flickering with the debugging buttons in the top right, as can be seen in the video, but I think that's been there for a while.

This can probably be closed now. Maybe @DexterLagan can confirm if it's fixed for them as well?
