VSwitch plugin sometimes causes segfault #1150

Closed JordanL2 closed 7 months ago

JordanL2 commented 3 years ago

Occurs in current git master, and in 0.7.0 stable. Arch linux.

Sometimes, when I try moving to a different workspace (usually going down) Wayfire crashes. All that I see in the logs is:

EE 18-04-21 16:43:24.357 - [src/main.cpp:141] Fatal error: Segmentation fault
EE 18-04-21 16:43:24.401 - #1  signal_handler(int) ../src/main.cpp:143
EE 18-04-21 16:43:24.416 - #2  __restore_rt sigaction.c:?
EE 18-04-21 16:43:24.416 - #3  [0x5567d3ad7588]
(EE) failed to read Wayland events: Broken pipe

I'm (now) currently running Wayfire built with full debugging support and haven't managed to reproduce it yet, hopefully it's not a bug that only occurs when debugging isn't enabled...

JordanL2 commented 3 years ago

I've managed to figure out a sequence of steps that reproduces it every time, and I've captured the log with full debugging enabled.

Steps are:

  1. Update the wayfire.ini config, causing wayfire to reload config - screen turns black for a second when this happens
  2. Use vswitcher to move to a different workspace

This causes the crash every time. If I move a window to another monitor after the config reloads, this stops it crashing somehow.

Disabling the scale plugin stops the crash happening.

Also, when I re-enable scale and wayfire reloads the config, the crash doesn't happen if I then change workspaces. I have to cause another reload first.

Please re-open the issue with a new stack trace if the issue persists on newer Wayfire versions.
