Bug ID: 413094
Summary: Extreme lag spikes with Nvidia nonfree driver
Product: kwin
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: grzesiek.jedenas...@outlook.com
Target Milestone: ---
SUMMARY
During using Plasma 5+KWin on Nvidia GTX 660 and nonfree driver, extreme lag
spikes happen. I will show few examples in attached video.
If I uninstall driver and take out the video card, it works fine on integrated
graphics.
Also using nouveau is smooth, but it crashes my machine very often and only
SysRq works. Also, I don't use that card to stare at desktop but also to play
games (and that's quite impossible with nouveau).

STEPS TO REPRODUCE
1. Get GTX 660.
2. Install Debian 10 with KDE.
3. Install nonfree driver (nvidia-driver).
4. Try to use it for a day. If you can't see it, use KWin FPS meter applet.
OBSERVED RESULT
Extreme lag spikes.
EXPECTED RESULT
Smooth experience.
