wlr/taskbar empty after switching monitor inputs on Hyprland

[SherLock707]

Issue:

With few apps opened on desktop if I switch my monitors input from HDMI-1 to HDMI-2 then back to HDMI-1, all icons in task bar disappears leaving a minimum size widget .

HDMI-1 : PC : Arch hyprland with waybar
HDMI-2 : Laptop

Expected:

• All Opened app icons present in taskbar

Actual:

• All opened app icon disappeared from taskbar
  
  Only the newly opened opened app icon present in taskbar.

Possibly fixed by PR #3393, now in master branch. Any chance you can try this again?

Might be my issue is different, but I am having something similar. I swap inputs to my monitor using a kvm and everything will be gone when I switch back. Have to kill and restart waybar.

Another bug requires I restart waybar via hyprctl dispatch exec, and no taskbar icons appear when doing so. It seems reproducable whenever I'm using pkill or killall (without -SIGUSR2).
