User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0
Steps to reproduce:
Open a tab to a page with drop downs, try to change the entry.
Nothing happens, selecting with mouse will not work. One can use <tab> however mouse left click on the drop down fails, with dual screen on linux Fedora 31.
The drop down should display alternatives.
Wayland issue, please use firefox-x11 package as a workaround for now.
Jan, can you look at it please?
I can confirm this issue (wayland only, X11 works fine). Downgrading from 71 -> 70 shows that the bug was introduced in between those two versions.
Testing done on arch linux (kenel 5.3 and 5.4, mesa 19.3-rc5, webrender enabled and disabled, amdgpu and i915 backends both tested)
On Ubuntu Eoan (19.10) with triple-screen, same issue when launched with MOZ_ENABLE_WAYLAND=1
firefox 71.0+build5-0ubuntu0.19.10.1 amd64

Please try the nightly. This issue should be fixed in bug 1597990.
