Description Martin Collins 2017-10-11 14:32:26 UTC 
New bug in plasmashell 5.8.7
After resuming from suspend the bottom few pixels of the panel are black and also a small rectangle in the bottom right of the screen which obscures the last digit of the clock.
Restarting plasmashell fixes it.
I am running nouveau graphics driver.

The black bar runs all along the bottom of the screen.
Comment 3 Martin Collins 2017-10-19 17:07:31 UTC 
Still does it with plasmashell 5.10.5
Comment 4 David Edmundson 2017-10-19 17:35:36 UTC 
Ah, I've seen that too.

Can't see a duplicate bug for it :/

alphaMask() gets out of sync. 
Only an issue with compositing off.

If you want a fast fix, wipe anything with plasma in the name in ~/.cache

Wiping ~/.cache didn't work. I noticed this in my syslog:

This was fixed for a while but it is broken again in 5.12.5

Wasn't a similar bug fixed some time ago?
Comment 8 Nate Graham 2022-06-25 19:14:32 UTC 
A lot has changed since this bug was filed. Is it still reproducible for you in Plasma 5.24 (the latest LTS version) or 5.25 (the latest version, period)?
Comment 9 Martin Collins 2022-06-25 19:34:30 UTC 
I am on 5.24.5 now, but have not seen this happen in a long time.
Comment 10 Nate Graham 2022-06-25 19:36:43 UTC 
Cool, thanks. Let's call it fixed.
