Bug ID: 502259
Summary: Extreme memory leakage when using KDE with
kwin_wayland in multi-monitor setup
Classification: Plasma
Product: kwin
Version: 6.3.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: filipembed...@gmail.com
Target Milestone: ---
SUMMARY
I have noticed that something has been leaking memory on my laptop. I noticed
it first time when my laptop started crashing and glitching, I checked htop and
have seen that my RAM usage has been maxed out. After some further
investigation, I noticed that it occurs when I plug in my HDMI cable of my
external monitor. After some time, the memory starts to leak a lot. I figured
out that when I unplug my HDMI cable the memory is not freed, but when I plug
it back I noticed that memory usage drops in that moment (like something
reallocates used memory). However, on the other side, when I reboot the laptop
with cable already plugged in, I don't see that memory leakage anymore. Like
there is a problem with the plugging and unplugging the HDMI cable.
STEPS TO REPRODUCE
1. Power on the laptop with the unplugged HDMI cable
2. Power up the monitor with the cable unplugged from monitor
3. Plug in the cable and open some tabs in Browser (or anything else that will
faster consume some memory)
EXPECTED RESULT
After 10-20 minutes, the leakage should be noticed. The used memory will only
rise.
