> User mentioned in Comment 2 said that eventually flicker go away if tablet is powered on too, but I didn't tried that.

Tested this couple of days ago with rc3, I tried to left Lenovo Miix320-10ICR
powered on with flicker screen for two hours, and flicker doesn't go away. So
this does not help in my case.

> Poweroff tablet for a ten minutes or so.

It seems like this was necessary with Linux 5.0/5.1, but with more recent
kernels (Linux 5.3 and drm-tip) simple reboot was sufficient, at least latest
two times I tried to do this.

Please let me know if I should test few latest Linux releases to find out since
when reboot starting to be sufficient to workaround this issue.
