[Bug] Segsegv when moving window #16

Open 1cekrim opened 9 months ago

1cekrim commented 9 months ago

Description

When I quickly repeat window movement with Super + PageUp/PageDown, segsegv occurs.

Budgie version

budgie-desktop 10.8.2

Operating System

6.6.1-arch1-1

Steps to reproduce the issue

  1. Install arch and budgie with archinstall from the official iso
  2. Open several windows to increase the graphics load
  3. In this state, if I press Super+PageUp/PageDown, a slight stutter occurs, but if I repeat this, it crashes and logs out.

Actual result

dmesg:

https://github.com/BuddiesOfBudgie/magpie/blob/79ad959021bc3d8d95f6f2f0d630116116f6d119/src/core/workspace.c#L732

Likely the crash is here. So it sounds like the workspace being checked is invalid, probably because of such a fast switch. See if you can reproduce the issue with animations turned off via budgie desktop settings.

Workspace animation is managed in budgie desktop. Could be a timing issue.

1cekrim commented 9 months ago

Turning off the animation definitely solved the problem. Thank you. Additionally, after some testing, I found that quickly clicking Super+PageUp or Super+PageDown twice with the Wine app running can trigger the issue. It does not occur when the Wine apps are not turned on, so it seems to be a compatibility issue. I will report when I find out more.
