Bug ID: 517625
Summary: Shmem Memory Leak - Plasmashell - Wayland
Classification: Plasma
Product: plasmashell
Version First 6.6.2
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
`Shmem` balloons from 200MB to 1500MB in 5 days, after all windows are closed.
Restarting plasmashell service brings `Shmem` back down to 300MB.
(Still waiting for KWin Wayland to be `--replace`able like KWin X11 could,
instead of booting me back to SDDM)
STEPS TO REPRODUCE
1. Log in
2. grep Shmem < /proc/meminfo
3. Use as-normal (including hovering mouse over application panel playing
video. Assuming this is still GEM-related)
4. Close all windows (except for 1 terminal)
5. grep Shmem < /proc/meminfo
6. Restart plasmashell service
7. grep Shmem < /proc/meminfo
OBSERVED RESULT
1. Shmem: 192312 kB
2. Use as-normal
*5 days later*
3. Close all windows (except for 1 terminal)
4. Shmem: 1456248 kB
5. Restart plasmashell
6. Shmem: 353168 kB //maybe kwin_wayland too?
Logging out/in results in "1.".
EXPECTED RESULT
1. Shmem: 192312 kB
2. <use as normal>
3. <close all windows>
4. Shmem: <Near> 192312 kB
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.6.2
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2
ADDITIONAL INFORMATION
Original issue:
-https://bugs.kde.org/show_bug.cgi?id=423372 //X11. Can probably be closed
since I don't intend on going back to X11
--https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/2924#note_3178944
X11->Wayland (never resolved)
---Sunreclaim/Unevictable are not an issue after moving to Wayland.
(maybe similar to https://bugs.kde.org/show_bug.cgi?id=505240, but no GPU
hogging)
