SUMMARY After recent updates to kwin master, kwin_wayland spams "kwin_wayland[1812]: kwin_scene_opengl: 0x1: GL_INVALID_VALUE in glScissor" in the logs. I didn't notice any visible graphical glitches. STEPS TO REPRODUCE OBSERVED RESULT EXPECTED RESULT The error causing this message should be fixed SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.80 KDE Frameworks Version: 6.6.0 Qt Version: 6.8.0 Kernel Version: 6.10.5-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 20 × 13th Gen Intel® Core™ i9-13900H Memory: 15.2 GiB of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: ASUSTeK COMPUTER INC.

Any clues what triggers it? As is, I'm afraid the bug report is not actionable.

I find the same problem, not critical as everything is working as it should, but there are a lot of messages in journal with this content: kwin_scene_opengl: 0x1: GL_INVALID_VALUE in glScissor It happens whenever I place the mouse over the taskbar, and specially when I trigger the windows presentation in left top corner.

This is almost certainly fallout from https://invent.kde.org/plasma/kwin/-/merge_requests/6273, the code doesn't clip damage to the framebuffer
For me it's `kwin_wayland[23058]: kwin_scene_opengl: 0x2: GL_INVALID_VALUE in glScissor` on Operating System: openSUSE Tumbleweed 20241007 KDE Plasma Version: 6.2.0 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3 Kernel Version: 6.11.2-1-default (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX 580 Series
The same with my prime system with intel iGPU and nvidia dGPU. This log was output as soon as user desktop is starting
