I just updated my laptop running Manjaro GNOME, and I noticed that Linux 5.9.3 was available. So I decided to update the kernel at the same time. Unfortunately, when I restarted my computer, the screen started to blink and some elements were moving by themselves. I restarted the computer again, same problem. The problem disappeared when I put Linux 5.8.1 back on. I also noticed that my Bluetooth mouse stopped working with Linux59.
Here is a video of the problem : swisstransfer[dot]com/d/e98ae728-4de3-4194-8f1b-bb77f9864bd4 (file available 30 days). Boot logs and hardware info are available here : paste.ubuntu[dot]com/p/XSDngbRPgR/.
Replace the [dot] with dots, I can’t send links, my account is probably too new.
Thanking you in advance for your answers
