Created attachment 171012 [details] video showing visual bugs in Plasma when software rendering is active SUMMARY Setting Plasma Rendering Backend to "Software" causes many issues, including a reproducible crash in kwin_wayland as well as visual bugs in various applications. STEPS TO REPRODUCE kwin_wayland crash: 1. In the 'Plasma Renderer' settings application/dialog, set "Rendering Backend" to "Software" 2. Grab any window and drag it to the top of the screen to maximize it More details here: https://discussion.fedoraproject.org/t/fixed-updating-kinoite-broke-things-not-even-a-rollback-fixes-it/123578 OBSERVED RESULT kwin_wayland crashes / visual glitches occur (see attached video) EXPECTED RESULT window is maximized without crashing + visual glitches don't happen SOFTWARE/OS VERSIONS I'm using Fedora Kinoite Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.5-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 7900 12-Core Processor Memory: 61.9 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4090/PCIe/SSE2 Manufacturer: Gigabyte Technology Co., Ltd.
