For a while now I have the following problem. After boot and login things look OK,
however moving any window shows terrible artifacts.
Here is an example using xterm.

I open a small xterm
Looks OK.

I do a reverse search: ^Rls -l
At this point the whole line is filled with a repeated quote character. Doing other things will
repeat a substring of what the text holds. Hitting 'end' key will show the full text followed by the quotes.
Very difficult to work when parts of the text disappear or get mangled.

Moving on, I grab the window and move it a bit. The whole window is filled with a pattern, here is is
just a color pattern.
If the window gets repainted it looks OK until I move it again. The only way I found so far to fix it is to restart X,
so logout then login, not nice.
I am on fc30, fully up-to-date, using the onboard graphics of a 'Gigabyte Z390 UD' with a "Core i7-9700".
TIA
Not sure what kernel. If still pre 5.2 boot with i915.alpha_support=1 kernel parameter.
