Hi,

Running Tumbleweed with KDE Plasma on a Yoga Slim 7 (AMD Ryzen), I have an
issue with recent updates, since snapshot 20210305 (I suspect the kernel update
to 5.11.2?).

When waking from sleep, my laptop screen is completely glitchy (mainly back,
with random aspects of my desktop placed randomly on the screen, and the cursor
is a rectangle of random pixels), and I cannot unlock the computer, nor access
TTY (using Ctrl+Alt+F1). After some time, the screen goes black and the cursor
appears again (and can be moved), but the laptop is still completely
unresponsive, including TTY.

I tested each snapshot since then, nothing fixed the issue and I always have to
rollback to previous snapshots.

Let me know if I can provide any more useful information.
