Only half of the screen gets the effect

[sefeng211]

Hi all,

So I've a dual monitor setup. Both of them have the same resolution (4k), one horizontal and one vertical.

When I run picom, event without any configuration, I see only half of both screens got the effect. The other half becomes black.

Running xrander --current I got

Screen 0: minimum 8 x 8, current 6000 x 3840, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)

How do I solve this? Thanks!

a screenshot/photo of the current behavior would be helpful. currently it sounds like a bug in picom.

I am running picom vgit-b700a.

Do I see it correctly that the bottom half of your screens is black? Will programs show there and just the background is missing? Or won't anything be drawn there?
