Black screen after update

So, I’m using KDE on a macbook air from 2013. I ran an update today and I can log in, but as soon as I open anything, 5 seconds later the panel+background go black.

If I opened anything in that 5 seconds, that stays on screen. I can still log out by pressing my shortcuts and then log back in and the same thing happens.

I’m not sure what to do.

downgrade mesa and eventually mesa-vdpau try to reach TTY ctrl-alt-f(x)

downgrade mesa mesa-vdpau or only mesa, mesa is the issue

This worked, thank you

Mesa was fixed in 20.0.7-2
