Hi!
I've been experiencing the same set of problems (as shown on the
videos)
lately and I think it might be kernel/video drivers related. It
started
to manifest when I upgraded linux-libre to one of the latest
versions
(5.9 -> 5.10 not sure exactly which one was it). I've resolved
it by
downgrading to linux-libre-5.4.
I have Lenovo Thinkad X240 with this graphics card: 00:02.0 VGA
compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics
Controller (rev 0b)
Yes, same machine and same graphics card. Makes sense, thank you
very much for the hint!
