Summary: krfb starts gobbling cpu when gaming
Classification: Applications
Product: krfb
Version: 24.12.2
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: grundleb...@googlemail.com

Target Milestone: ---
SUMMARY
krfb starts gobbling around 50-60% of one thread when starting a game, much
like https://bugs.kde.org/show_bug.cgi?id=464800 . krfb also had no clients
connected so could be related to https://bugs.kde.org/show_bug.cgi?id=464802 as
well. Could be related to using gamescope
https://github.com/ValveSoftware/gamescope .
STEPS TO REPRODUCE
1. load steam, start helldivers 2. using gamescope.
2. looking into whats making it laggy I discovered krfb gobbling lots of cpu
for no reason.
OBSERVED RESULT
gobbling cpu. stopping this gave me ~5fps back. go figure.
EXPECTED RESULT
krfb justs sits there eating nothing since no client is connected.
