After enabling second monitor, the new area is not rendered correctly

Suyooo commented 6 days ago

When changing monitor configuration, such as enabling additional monitors or rotating one, picom seems to not render the new area. Occurs since c96ca0a.

Platform

Debian Trixie (testing) x86_64

GPU, drivers, and screen setup

Nvidia GTX 970 with proprietary drivers 550.54.14, Mesa 24.0.8-1. Triple monitor, side-by-side, configured via xrandr.

I tried to change some of the GLX backend options, but none seemed to have an effect.

Steps of reproduction

Start picom with one monitor active.
Enable a second monitor to the right of the first.

Expected behavior

The new monitor is correctly displayed.

Current Behavior

The new area is not correctly rendered until picom is restarted.

Log file

This is a logfile of starting picom, enabling a second monitor, then exiting picom again. Log level set to Debug, if you feel like a full trace would help, let me know and I can record one.

picom-bad.log

For comparison, this is the same sequence but with picom at 88c8ba8 where the error does not occur, in case it helps.

picom-good.log

Video recording

The video shows me enabling the right monitor, which does not show the window that is supposed to be there, and trying to move another window onto it. At 18 seconds, I restart picom, and it works fine afterwards.
