Bug ID: 450770
Summary: Kwin Plastik style leaks GPU memory in Xorg on window
resize
Product: kwin
Version: 5.24.2
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: aurorae
Assignee: kwin-bugs-n...@kde.org
Reporter: spa...@wp.pl
Target Milestone: ---
SUMMARY
Resizing any window with Plastik style on X11 uses more and more GPU memory. It
doesn't happen with Oxygen and Breeze styles. The GPU memory can be freed on
kwin_x11 restart. I can observe this problem on Radeon (Mesa) and NVIDIA with
proprietary drivers.
STEPS TO REPRODUCE
1. Run X11 session.
2. Set Plastik KWin style.
3. Resize any window for a long time (e.g 1 minute).
OBSERVED RESULT
GPU memory usage increases on every window resize.
EXPECTED RESULT
GPU memory usage doesn't increase on window resize.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.12.2
Mesa: 21.3.6
Nvidia: 510.54
ADDITIONAL INFORMATION
GPU memory monitoring:
- `watch -t -n 1 "vulkaninfo 2> /dev/null | grep -A 2 'memoryHeaps\['"`
- `watch -n 1 nvidia-smi`
- `sudo radeontop`
AMD Radeon 6900XT, before resizing:
memoryHeaps[0]:
size = 17163091968 (0x3ff000000) (15.98 GiB)
budget = 17118306304 (0x3fc54a000) (15.94 GiB)

memoryHeaps[1]:
size = 17163091968 (0x3ff000000) (15.98 GiB)
budget = 14769287168 (0x370517000) (13.75 GiB)
AMD Radeon 6900XT, after 60 seconds of resizing:
memoryHeaps[0]:
size = 17163091968 (0x3ff000000) (15.98 GiB)
budget = 8399335424 (0x1f4a3b000) (7.82 GiB)

memoryHeaps[1]:
size = 17163091968 (0x3ff000000) (15.98 GiB)
budget = 1272381440 (0x4bd70000) (1.18 GiB)
It consumed over 16 GiB memory visible by the GPU!
