Please attach the output of > drm_info and > kscreen-doctor -o and > vulkaninfo Both Bazaar and Ptyxis are GTK4 apps that use Vulkan. It sounds like there could be a problem with explicit sync. If you run for example > vkcube --wsi wayland does that also show glitches? When you wrote "Switching the monitor to video output from the mother board", are you just switching the display or also rebooting in between? |
Created attachment 187427 [details] A video showing glitches in Bazzar SUMMARY On Aurora Linux two applications, Bazzar and the pyxis terminal show glitches that look like compositor problems when using the Intel Arc B580 graphics card. This occured after the change from Plasma 6.4 to 6.5. Other applications do not seem to have this issue. Switching the monitor to video output from the mother board (CPU video) eliminates the issue. STEPS TO REPRODUCE 1. Open a terminal or the Bazzar store 2. Move mouse in the opened windows, or wait a bit 3. OBSERVED RESULT Windows exhibit graphic artifacts including white and colored blocks, and broken text EXPECTED RESULT Clean display of window content SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Aurora 43 KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 ADDITIONAL INFORMATION
