Title:
firefox fullscreen display glitches with hidpi scalingb
Status in firefox package in Ubuntu:
New
Bug description:
When I go on fullscreen on a video on Firefox with HIDPI scaling
factors more than 100%, I get odd behavior of the fullscreen video.
This behavior is not seen on Chrome, or if the scaling factor is 100%.
Basically, it seems like there is some resizing of the video to a
smaller window in the upper left, and when I escape fullscreen,
sometimes the firefox window itself is scaled off the display.
At times, this glitches a few times and eventually resets, sometimes,
it stays this way. It appears to have changed behavior multiple times
over the past few weeks of updates of various parts of the stack, and
may just be narrowed down for me now to something repeatable. For
instance sometimes I could not trigger it until I pressed volume up or
volume down. Now it appears to happen just waiting for a few seconds
on the running video.
This is on X11, and on focal with the latest updates as of today
2020-04-01.
Happy to debug more, not sure what information is useful.
thanks!
