Bug ID: 428429 Summary: Graphical errors that appear somewhat frequently Product: kwin Version: 5.20.2 Platform: Neon Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: scene-opengl Assignee: kwin-bugs-n...@kde.org Reporter: mich...@erikgranger.name Target Milestone: --- SUMMARY With an AMD RX590, using the Oibaf PPA drivers, I'll experience graphical artifacts every 10-20 minutes or so. It will appear as though a portion of the screen is stuck in place, and will ignore the rest of the screen around it. For instance, if using a web browser, you can scroll down but part of the window won't update to indicate that you have, while another part does. I managed to grab a screenshot of this effect (occurring within the shader wallpaper). https://i.imgur.com/rFzJYpz.png If I go to the compositor settings, and toggle the rendering backend to OpenGL 2.0, apply, then switch it back to OpenGL 3.1, this fixes all graphical errors temporarily.

Watch as the graphical errors appear OBSERVED RESULT System becomes graphically buggy, some portions of the screen refuse to change when the window changes EXPECTED RESULT System should not become graphically buggy SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.4.0-51-generic KDE Plasma Version: 5.20.2 KDE Frameworks Version: 5.75.9 Qt Version: 5.15.0 ADDITIONAL INFORMATION Using Oibaf's AMD drivers from his PPA -- You are receiving this mail because: You are watching all bug changes.
