phosh: incorrect keyboard input in Xwayland apps

Hello,

I am using phosh on the pinephone.

I am having trouble with keyboard input on Xwayland apps. So for example, running firefox with MOZ_ENABLE_WAYLAND=0 (disabling experimental wayland support) causes phosh's virtual keyboard inputs to be slow and not match what I am pressing. In contrast, if I run firefox with MOZ_ENABLE_WAYLAND=1 (enabling experimental wayland support), phosh's virtual keyboard works perfectly fine.

Firefox is the only program I know how to switch from Xwayland to wayland. But I've had keyboard input issues with other programs and I think it's a result of Xwayland. For example, another program Ive had the bad keyboard input issue is in pinentry-gtk-2 - I dont know how to verify if this program is running under Xwayland.

Please let me know if I can help debug and/or solve this issue.

Thank you!
