In a gnome-shell wayland session I’m not able to perform a single mouse click.

I bisected this bug to commit e5ff036c6751c39ee008ca7db47b3ce4d7a38a15 (st/dri:
Add support for BGR[A/X]1010102 formats.).

After reverting commits 2d8e1a6a277cb1684d76210351147f5e7858c8b2 (child commit)
and e5ff036c6751c39ee008ca7db47b3ce4d7a38a15 I can perform mouse clicks again.

commit 2d8e1a6a277cb1684d76210351147f5e7858c8b2
    st/dri: Add option to control exposure of 10 bpc color configs.
