Description of problem: I noticed that after the upgrade from Fedora 30 to 31 (switch to Firefox on Wayland by default) my noScript (Firefox Addon) UI was not working properly. The Bug is specific to Firefox on Wayland since one can work around the bug using Firefox on X11. I filed a bug against the addon (https://github.com/hackademix/noscript/issues/112#). After some discussion hackademix figured out, that this Bug is NOT ADDON SPECIFIC but FEDORA specific for addon UI elements placed to the left of the URL bar in Firefox for Wayland. It is not present on Firefox for Wayland on e.g. Ubuntu. Version-Release number of selected component (if applicable): Firefox 70 and 71 tested Fedora 31 How reproducible: See below Steps to Reproduce: 1. Use Firefox on Wayland under Fedora 31 and install any addon with a UI (e.g. uBlock, noScript, Tab Session Manager). 2. customize your Firefox UI to have the addon icon the left of the URL bar. 3. Try to use the addon UI (try to click on the any element of the 'drop down' UI of the addon) Actual results: There is an offset between the drawn UI and the action buttons. Thus the UI is not usable. Expected results: The UI should work as expected (action button directly below the drawn icon). Additional info: Make sure to read hackademix post and have a look at the screenshots provided on Github. https://github.com/hackademix/noscript/issues/112#issuecomment-564775368
Jan, can you look at it please? Thanks.
The same behaviour is also true for firefox built-in UI dropdown elements like the Downloads menu. If you customize the UI such that the Download icon is to the left of the URL bar the little triangle (signalling that this UI dropdown menu comes out of the icon) which is usually directly under the icon as an offset.

I tested this by installing the update via: $ sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2020-c5f18c9518 but the UI offset regression is NOT FULLY fixed for me. The UI is usable again but the little triangle (which should be directly under the icon the dropdown menu is coming out) still has an offset. To conclude: The functionality got fixed but there are some visual regressions left. I also tested Firefox Nightly 74.0a1 (2020-01-16) (64-bit) directly from mozillas website: It got COMPLETLY FIXED. Is it possible to attach ScreenShots here?

The upstream version runs in xwayland, so the bug does not appear there at all. Currently the arrow issue is difficult to fix, because the GTK moves the window from negative coordinates (ie. the panel showing outside of the window to the x zero position while the Firefox has already the arrow placed). We're also unable to detect the edge of the screen because the absolute position of the window is not available under Wayland, so Firefox cannot flip the window along y axis as it does under xwayland/xorg. Currently Firefox is not designed that the panels are changing positions after it calculates it's dimensions. There's still a room for some improvement but we'll hardly accomplish the same behaviour we see under xwayland/xorg.
