Description Steven Haigh 2019-11-26 15:34:00 UTC
When browsing sites that use SELECT dropdowns, the dropdown box cannot be interacted with using the mouse. Using the keyboard to select a select box, then using the up / down arrow to change options works - but you cannot select / change the contents of the select box via the mouse.

This works fine if you start firefox with: GDK_BACKEND=x11 firefox

GPU is an AMD RX5700XT.

An example web site is:

 $  rpm -qa | grep mesa | sort

 $  rpm -qa | grep llvm | sort

 $  lspci | grep VGA

I'm seeing the same issue here as well.  firefox-70.0.1-4.fc31.x86_64 on Fedora 31, Wayland, Intel GPU (Intel Corporation HD Graphics 620 (rev 02)).

It happens with or without hardware acceleration enabled in Firefox and is a recent regression.

Comment 2 Scott Williams 2019-11-26 20:54:30 UTC
Another workaround is to install the "firefox-x11" package and start firefox with the "firefox-x11" command.  This wrapper just sets MOZ_DISABLE_WAYLAND=1, which I assume achieves something similar to GDK_BACKEND=x11 mentioned in OP.
