#55 Kernel 6.11 (& 6.12) freezes COSMIC when minimizing / maximizing windows on Fedora 40 & 41 (e.g. Firefox)
Opened by nivaldron. Modified

The problem got solved when upgrading to Fedora 41.

(using an AMD RDNA 2 GPU)

Update: The problem wasn't solved yet, see comment below.


Seems like it's still freezing on 41. For some reason an old cosmic-comp was installed after upgrading to Fedora 41. Only workaround for now is to use sudo dnf downgrade cosmic-comp which will install then version 0.1.0~git20240514.00.36bf611 from the fedora repo or to downgrade to a kernel that's not higher than kernel 6.10.

With the recent cosmic-comp update, you can edit the (hidden) .bashrc file in your home folder & add at the bottom of it:

export COSMIC_DISABLE_DIRECT_SCANOUT=true

This will disable direct-scanout & fix the freezing. Just remove this entry, once the problem is fixed in a future update.

@ryanabx Maybe this information can be added to the description page? I think many people could be affected by it.
