Black Screen while navigating the Desktop #331

Closed RayJW closed 3 months ago

RayJW commented 6 months ago

I'm currently trying out Cosmic on Fedora 40 installed via the COPR. While I know that this is not officially packaged, this might still help to find bugs.

On my device, the screen regularly goes completely black while using the desktop. There's not really a pattern to the issue, although I feel like a lot of times it happens when e.g. opening an applet or an applet spawns a new window, like the log-out prompt. The only way to get back output I was able to find so far is switching to a different TTY and then back.

I have a little journal output here, somewhere in this log the issue happened, although I can't say what specifically is just noise and what might be related.

What might be related, it's a laptop, and I'm using 175% scaling with a 90 Hz display

I can't reproduce this issue any more with the newest builds and am therefore closing this, good work! :)
