Bug ID: 368066
Summary: kwin causes X to leak video memory
Product: kwin
Version: 5.7.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: glx
Assignee: kwin-bugs-n...@kde.org
Reporter: oneof...@gmail.com
Using kwin 5.7.4, but applies to 5.7.3, after few hours of usage (chrome, wine
and hipchat) the system becomes unresponsive and after some tracking I noticed
that running nvidia-smi prints that Xorg is using 7.5g of GPU memory.
Restarting kwin doesn't free that memory, only restarting X.
Reproducible: Always
Steps to Reproduce:
1. Use KF5.
2. Use the computer for few hours (Chrome, VSCode, HipChat4 and wine)
Actual Results:
Random windows turns completely black and the system becomes mostly
unresponsive until I kill X.
Expected Results:
Well, not make X use up all my GPU memory.
This only happens with kwin, using Gnome 3 and LXDE with openbox does not
trigger this bug.
nvidia-* 370.23, xorg-server 1.18.4, the card is Gigabyte G1 1080.
