Description of problem: Firefox crashes when dragged over (or near) the boundary of two displays in a dual display setup, where the displays are differently scaled. Version-Release number of selected component (if applicable): firefox-100.0-2.fc36 How reproducible: Always afaict Steps to Reproduce: 1. Have two displays with different scaling. I have a laptop with high resolution display scaled at 125% in Gnome settings and a 24" monitor scaled at 100%. With these settings the displays appear to be at a similar scale, i.e. the fonts appear about the same size on both displays 2. Open Firefox on one display and browse to any page. 3. Drag Firefox with the mouse so that the window moves partially to the other display Actual results: Firefox immediately crashes Expected results: 4. Firefox should not crash This only appears to happen when using Wayland. If I start with firefox-x11, then Firefox does not crash. If both displays have the same scaling, i.e. 100%, then Firtefox does not crash. I never saw this behaviour in Fedora 35. Additional info:
Observed here in Wayland GNOME with: firefox-100.0-2.fc36.x86_64 mutter-42.0-6.fc36.x86_64 gnome-shell-42.0-3.fc36.x86_64
I don't know if it's the same but I'm seeing a lot of crashes since upgrading to F36 on a system with a high resolution display scaled at 125% but mine seem to have been triggered either when I switch to a different workspace or when I switch user or wake the display from sleep - basically anything triggers a rerender of the screen. It doesn't always happen when I do those things but it always seems to be one of those that triggers it. Unfortunately I don't have a backtrace yet because firefox steals the crashes for Mozilla's crash reporter...
Can you attach any of the crashes from Mozilla? https://fedoraproject.org/wiki/How_to_debug_Firefox_problems#Collect_information_for_a_bug_report Thanks.
I think https://crash-stats.mozilla.org/report/index/7022d42d-d332-4b1d-9de0-b39220220508 is one of mine. Certainly it has a highly suspicious crash reason of: wl_surface@97: error 2: Buffer size (1427x1036) must be an integer multiple of the buffer_scale (2)

Added to firefox-100.0-4
My bug report, https://crash-stats.mozilla.org/report/index/ab15e269-46f2-48da-aa2b-1cd1f0220509 has the same crash reason: wl_surface@50: error 2: Buffer size (1426x1015) must be an integer multiple of the buffer_scale (2)
