SUMMARY When changing the global theme via system settings, say from Breeze to Breeze Dark, the screen becomes corrupted, rendering incorrect textures or compositing textures in the wrong place. STEPS TO REPRODUCE 1. Start a plasma wayland session 2. Change the global theme. OBSERVED RESULT Corrupt desktop compositing. EXPECTED RESULT Correct desktop compositing. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.15.9 Kernel Version: 6.3.5-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 32 × AMD Ryzen 9 7950X3D 16-Core Processor Memory: 62.5 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4090/PCIe/SSE2 Manufacturer: ASUS ADDITIONAL INFORMATION Linux: 6.3.5-arch1-1 Nvidia drivers: 530.41.03-15 Taking a screenshot with Spectacle does not show corruption, it is only on-screen.
It is less reproducible than I initially thought. There may need to be some memory pressure or some extended use of the session for the issue to repro. I'll keep trying to figure out a reliable method. Once the system is in a bad place, it repros reliably. I have a photo I can share of it, though I had to anonymize it.
