Steps of reproduction

autostart picom

Expected behavior

To work without filling xsession-errors

Current Behavior

Filling up xsession-errors with a lot of :

Xlib: ignoring invalid extension event 161 Xlib: ignoring invalid extension event 148

Other details

I can avoid those errors by launching picom manually with picom -b after entering the session but as soon as it's autostarted I get the spams.

Let me know if more infos are needed.

Thank you.

Try picom from next branch. I remember we fixed that right here.

[absolutelynothelix]

closing as it's already fixed in the next branch.
