Description Marcus Husar 2018-01-27 13:10:40 UTC
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.

commit e5ff036c6751c39ee008ca7db47b3ce4d7a38a15
    st/dri: Add support for BGR[A/X]1010102 formats.

Comment 2 Michel Dänzer 2018-01-30 10:43:33 UTC
This is a gnome-shell/mutter/clutter bug, please report it there.

You can work around it by putting this in ~/.drirc:

    <device screen="0" driver="radeonsi">
        <application name="gnome-shell">
            <option name="allow_rgb10_configs" value="false" />
