fvwm-root doesn't work properly with picom

[pansy27]

Upfront Information

• Fvwm3 version: fvwm3 1.0.6 (1.0.5-3-g6ecbbadd)

• Linux distribution: Arch Linux

• Platform: Linux

Expected Behaviour

I was trying to set the wallpaper using fvwm-root and run picom.

Actual Behaviour

The wallpaper that got set by fvwm-root becomes grey colored if picom is started. This doesn't happen with nitrogen and hsetroot.

Enabling logging

Here's the log: https://pastebin.com/guJJGH6Z

Steps to Reproduce

• set wallpaper using fvwm-root
• start picom, the background set by fvwm-root becomes grey colored.
• config: https://pastebin.com/8iPmjVWX

Extra Information

• tried using picom without my picom config, still facing the same problem
• tried adding "fvwm" and "fvwm-root" to exceptions in picom config but to no avail
• my picom config: https://pastebin.com/jMDwajHT
• some screenshots:

Hi @pansy27

Yes indeed -- this is due to how fvwm-root sets the wallpaper -- and even then, this isn't something I'm inclined to fix. I'm sure there's better wallpaper setters. fvwm-root is good for what it does, but it is limited.

@ThomasAdam and @pansy27

Am I missing something, or:

• pansy27 didn't read man page for fvwm-root and use -r
• Thomas forgot that fvwm-root has this capability. :-)

For me, fvwm-root -r <img> works perfectly with picom.
