Bug ID: 483538 Summary: VRAM leak when repeatedly switching between window icons Classification: Plasma Product: plasmashell Version: 6.0.2 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Task Manager and Icons-Only Task Manager Assignee: plasma-b...@kde.org Reporter: aidas...@gmail.com CC: qydwhotm...@gmail.com Target Milestone: 1.0 SUMMARY So the VRAM usage leaks when repeatedly switching between window icons in the taskbar (I tested this with Konsole windows) I first noticed the issue when my RAM usage was unusually high on KDE 6 (so I checked radeontop and the GTT usage was over 3 GB which shouldn't happen in normal usage) So I did some testing and noticed that issue only happens in that scenario above (I did some more testing and noticed that disabling the 2 window options in Icons-only Task Manager prevents the VRAM leak) Hopefully this bug isn't Mesa-specific though (because I haven't tested a NVIDIA-only setup) STEPS TO REPRODUCE 1. Launch KWin Wayland 2. Make sure the 2 window options in Icons-only Task Manager are enabled 3. Open 2 Konsole windows (other apps should be fine too) 4. Hover over the 2 Konsole icons to generate the thumbnails 5. Click repeatedly between the 2 Konsole icons to switch between those Konsole windows (I think there's an unrelated segfault but the VRAM leak should be visible before then) OBSERVED RESULT The VRAM usage keeps growing with no limit (I managed to hit the 8 GB GTT limit) EXPECTED RESULT The VRAM usage should mostly stay the same SOFTWARE/OS VERSIONS Linux: 6.7.9-arch1-1 KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Mesa Version: 24.0.2 PipeWire Version: 1.0.3 -- You are receiving this mail because: You are watching all bug changes.
