• Version: fastcompmgr 0.4

Additional context

• does the bug happen without compositor? no
• does the bug happen using xcompmgr/compton/picom? no
  

PekWM Version is 0.3.0

I have tried fastcompmgr on raspberrypi os with pekwm as well, and no shadows there either. Opacity seems to work fine.

Shadows DO appear around windows generated from the parent window (preferences dialogs, find dialogs, context menus etc), but none of the root windows nor the window manager menu have shadows.

Thanks your the report. Until my pekwm issue is resolved, I suggest you try my proposed fix, to set params.attr.override_redirect = False; in src/PDecor.cc::PDecor::createParentWindow. Please report any potential side-effects.

Thanks, Tycho

Thank you for the helpful suggestion. Your workaround fixed all the shadow issues with no apparent side effects so far.

Thanks for the update. I'm happy to inform you that pekwm was updated and apparently fastcompmgr now correctly renders its shadows on normal windows.

Unfortunately no change; tested against pekwm-0.3.1 and fastcompmgr-0.5.1 also want to add same shadow issue exist with cwm-7.4 running fastcompmgr with suggested runsettings. Not much to discover in logging tty either..

pekwm release 0.3.1 does not include the fix. You have to clone the repo and build from source 😉. See also here.

same shadow issue exist with cwm-7.4

I cannot reproduce. On my Debian 12 with self-compiled cwm 7.4 I see no issues with shadows. What exactly is the problem?
