Public bug reported:
After update to firefox 89.0+build2-0ubuntu0.18.04.2, firefox appeared
completely broken. Restored history showed a bunch of blank or messed up
windows (NOT pages). My system is dual monitor with one monitor in
portrait mode.
As part of chasing a fix in a clean profile, got lucky and moved a
window to the main, landscape monitor and lo`, it drew correctly. Moving
window half on one monitor, half on second showed a working half and
messed up half.
Starting Firefox in safe-mode on second monitor worked correctly. Only
extension in place is uBlock Origin. See screenshot.
System is Bionic 18.04 updated 2021-06-05, after which issue noted.
Please advise if additional information is needed.
