You have been subscribed to a public bug:
Last week-end, after restarting my T470s running Ubuntu 19.10, I
experienced a lot of visual glitches that didn't occur before. However,
I had already noticed that some applications were unexpectedly freezing
for about 5-10 seconds.
I have already tried reinstalling xorg, without success. Then, I tried
running Ubuntu 20.04 from a USB stick, and the problem doesn't occur.
Today, I have upgraded Ubuntu to version 20.04 to see if it would fix
it, but without success again.
Note that when I restart the display server (Alt-F2 -> r -> Enter), it
fixes the problem (sometimes I have to restart it several times).
I would be happy to give you more information if you need.
