The stable version of GTK4 is 4.14.6. How is it possible for an unstable version to be released...? 😡🤬

[lazka]

4.16.1 is the latest stable release.

I can't reproduce the issue locally.

I have the same issue since updating to GTK 4.16 (on Windows). For example, the GTK Inspector now flickers; after changing tab I get flickers which display the tab I was on previously.

I have tried mingw64/mingw-w64-x86_64-gtk4 at versions 4.16.0-1 and 4.16.1-1, and they both exhibit the same issue.

Changing the renderer from the new OpenGL renderer back to the old OpenGL renderer with GSK_RENDERER=gl does not fix the issue.

I believe this is a GTK bug so I've filed a ticket on the dedicated bug-tracker.

thanks, perfect!

For the record, I'm on AMD, so maybe an Nvidia specific issue.

You beat me to it :) @hbiblia do you happen to have an NVidia GPU?

I have the same problem with version 4.16.1-2, but I was able to get it working with GSK_RENDERER=cairo. The other renderers have the same issue, and some are much worse.

Note: Version 4.14.x was working fine. The problem arose when I updated to 4.16.x.

I guess someone with nvidia hardware needs to bisect it.

I wonder if vulkan would work nowadays? Might be a workaround.

enabled in #22078, but it's not the default

I tested it with Vulkan, but the issue remains the same, so I stuck with GSK_RENDERER=cairo.
