Bug ID: 450913
Summary: System Freezes Completely while Launching GTK Based
Applications
Product: lattedock
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: mvourla...@gmail.com
Reporter: kdeb...@scmaruthi.trumail.one
Target Milestone: ---
SUMMARY
The System locks up completely when launching certain Applications whether
through the dock or the panel.
STEPS TO REPRODUCE
1. Launch latte-dock
2. Using the Panel or Dock (Latte Task or Task Manager) Launch GTK Applications
consecutively.
3. System would lock up immediately mostly on the 3rd launch.
OBSERVED RESULT
A complete freeze of the system.
EXPECTED RESULT
Applications launch normally.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Garuda Linux (ArchBased)
(available in About System)
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
The only thing common in all the freezes is that the app being launched is a
GTK based App.
This issue never occurs on other launch methods like using KRunner or launching
the App from terminal or launching it manually not using latte-dock, no matter
how much I stress the system by launching 10+ GTK Apps with multiple instances
on each where possible.
After consecutively crashing the system through the latte-dock after the 3rd
freeze, the system additionally defaults the kwin settings for the keyboard
shortcuts, window decorations and the GTK Gnome Application Style Options.
Troubleshooting Attempts (all had no effect):
1. running latte-dock in -d(ebug) mode.
Result: system locks up before output of any useful information.
Also Magic(SysRq) Keys don't work
2. Cleared the Cache using the default app command line and manually by
deleting the cache contents
3. Removed custom docks and panels and reset to the defaults.
4. Removed any externally dependent mount points which may cause lockups and
ran just with the bare minimum.
5. Disabled the Compositor
6. Used both the X11 drivers AMDGPU and the older ATI
7. Disabled all additional monitors
8. Tried to switch to Wayland
