Bug Description
This is a very wierd behavior I get on the Lenovo Yoga S940 after upgrading to 19.10.
This makes the laptop almost unusable with its own display.
This happens only on the laptop display, not on the external display.
The render of portions of the screen does not happen after some events (listed below) resulting in all or part of the screen not being re-rendered. The UX is that nothing happened, but it has.
This happens after:
* key-stroke while typing sometimes
* alt-tab
* shift-right to align window to the right
* ctrl-pgup/down to switch tab in multi tabs apps.
Please note that:
* screenshots can't see the problem
* also screenrecorder always seem ok, despite rendering being broken.

Update.
Today I experienced this: after suspending the laptop, now I do not experience broken rendering anymore.
This happened once before. Everytime I reboot, it comes back.
I'll try to identify a pattern here.
