Bug ID: 412428
Summary: Automatic "Allow Applications to Block Compositing"
seems to not be working
Product: kwin
Version: 5.16.90
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: jchevar...@gmail.com
Target Milestone: ---
I noticed after upgrading to 5.16.90 that automatic suspension of compositing
doesn't appear to be working for me anymore. I was going back to some more
freesync testing, and noticed it wasn't turning on in any game. This included
native games (Talos, SS3, etc), Feral Ports, and Proton games. I know at least
the native/Feral games used to send the flag to turn it off automatically,
which I thought was actually done at the SDL level. I have the settings "Allow
Applications to Block Compositing" ticked off in System Settings. I am not sure
when this actually broke (or if it is supposed to still work).
Steps to reproduce:
1. Open Steam
2. Launch any game in full screen
3. Notice that compositing isn't disabled (and things like Freesync are
blocked)
Reproducible:
Always for me.
Work around:
1) Press "shift" + "alt" + "f12"
2) Compositor turns off, things like Freesync immediately start working.
Operating System: Arch Linux (kde-unstable enabled, testing disabled)
