Lots of compositor lag when running firefox and there's no wallpaper set.

This could be an issue with cosmic-bg or cosmic-comp, not sure. My hunch is that cosmic-comp should never be slowed to a halt by a client application though.

NVIDIA RTX 4060 laptop GPU, AMD Ryzen CPU, Fedora 40

How to reproduce:

• Install cosmic components for the first time, so there's no background set
• Launch firefox
• Things slow to a halt, changing workspaces fixes this though.

How to work around:

• Set a background in cosmic-settings

Yes, but also extremely difficult to do.

Does this also happen, if cosmic-bg is simply not running?

the workaround works for me, strange no wallpaper can cause that

Fedora 40, cosmic-epoch copr

Definitely ran into this and the work-around of setting a background definitely fixes it.

Error sample before a background was set:

This is weird and likely good insight into why this is failing. I assume this is somehow caused by direct scanout.

[garrettjwilke]

also experienced this.

i had a wallpaper set up from an image on a folder. i ended up moving that folder, and the system used a gray background.

setting the image back made everything function well again.

AMD 8845HS, same issue.
