Bug ID: 478327
Summary: Dota 2 "Desktop effects were restarted due to a
graphics reset"
Classification: Plasma
Product: kwin
Version: 5.27.9
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: multi-screen
Assignee: kwin-bugs-n...@kde.org
Reporter: bradleyfou...@proton.me
Target Milestone: ---
When running Dota 2, an Alt+Tab or maybe a Steam chat message/other pop-up
creates a notification from KWin Window Manager saying "Desktop effects were
restarted due to a graphics reset". This then causes extreme lag if returning
to Dota and multiple Alt+Tab some times returns it to a usable state. I have
tested some other games and it doesn't seem to occur.
I was initially using Arch when this issue first occurred and I thought it was
a system update (not related to KDE) that caused it. I can confirm the issue is
happening on Fedora Kinoite, Fedora Workstation (KDE spin) and I think OpenSUSE
Tumbleweed as well. I am pretty sure this is a regression because I don't
remember this being a problem before (haven't used KDE for too long.)
This issue does not occur on GNOME, Sway or Hyprland.
I am on a laptop connected to an external monitor through USB-C -> DP (internal
monitor disabled and only using external.) VRR state doesn't stop the bug from
occurring. This issue doesn't seem to occur when only using the laptop monitor.
STEPS TO REPRODUCE
1. Launch Dota 2 with external monitor (not sure if cable type matters)
2. Alt+Tab or receive notification that steals focus
OBSERVED RESULT
KWin Window Manager notification pops up: "Desktop effects were restarted due
to a graphics reset" and when changing back to the game extreme lag/freeze
occurs. Alt+Tabbing multiple times sometimes returns the game to a playable
state.
EXPECTED RESULT
Alt+Tab without issues.
