Is this issue HW specific or you can se it everywhere?

Comment 2 Porygon 2019-03-14 22:33:28 UTC
Glitch was encountered on T480s (Intel UHD Graphics 620)

I attempted to reproduce on a desktop machine with a GTX1050ti and did not produce the same results, so it is probably HW specific.

Comment 3 Lyude 2019-03-18 20:51:04 UTC
Note: this is likely a duplicate of (since that bug affects anything with a UHD 620 GPU, not just the P50
Another note: This should be fixed with the DRM backport for RHEL8.0 or 8.1
