Steps of reproduction

1. Add unredir-if-possible = true; to the config.
2. Fullscreen a program such as urxvt

Expected behavior

Compositing for urxvt should stop, as should compositing for other programs

Current Behavior

URxvt still displays a non-transparent background. Everything else functions fine except for unredirect.

I have searched hours for a solution, and nothing was able to fix this. I can provide more info if needed.

Do you have by any chance more than one monitor attached to your system?

URxvt still displays a non-transparent background.

to make unredirection possible a fullscreen window has to be opaque.

I only have one 1920 x 1080 monitor

They are opaque though... I have it set so that it becomes opaque when I fullscreen a window. For example, URxvt is transparent unless fullscreen. If I fullscreen a window then compositing should stop for all other windows right? Currently, if I were to fullscreen URxvt and then open a new instance in another desktop view, the new instance still receives compositing.

@NextRank, a window has to be opaque by itself, i.e. have 24-bit depth.
