X.U.SpawnOnce: screen flickering after relogin xmonad

[ixzh]

Problem Description

I have a few windows spawned on WS 1 at start up. Using the following binding to exit xmonad and relogin, the screen is flickering and I can vaguely see the windows of last session.

However it seems if I wait for a while before login, things start normally ( no flickering ).

Expectec behavior: no flickering.

Steps to Reproduce

1. start a new session with reboot
2. quit xmonad by ctrl shift alt q
3. relogin immediately
4. screening flickering with reminiscent windows of last session

is it because GUIs are in the process of quitting even though xmonad quits successfully? anyway to save the waiting time?

Thank you

Would you be able to record a video (e.g. with your smartphone camera) of this? I'm like 95% sure this is an issue of the kernel, Xorg, or your display manager, but it'd help if we all knew exactly what we're talking about here.

Hi,

I restarted twice, and in the second time I reprocuded the flickering. Attached is the second time relogin.

While new windows are spawned in sequence, the windows of the last session are in the same place.

Okay there's some really weird shit going on, but definitely not in any way related to xmonad. :-)

Then the problem should be in my autostart.sh. I looked through it, and made sure each starts only once if process is not already running, especially Picom. Problem seems resolved at the moment. Thank you for the advice!
