[BUG]: Using Unreal Engine 5+ A phantom window appears and consumes a tile

[allora]

Summary

Using Unreal Engine 5 (seems any version will do this, unsure of unreal engine 4), starting the editor will create a phantom window. I can alt F4 on this window and close it, but it consumes a tile in Komorebi until then. Ultimately this is probably something unreal is doing, but i wonder if Komorebi can just.. ignore it heh

Hotkey Configuration

.shell powershell

Reload whkd configuration

alt + o : taskkill /f /im whkd.exe && start /b whkd # if shell is cmd

alt + o : taskkill /f /im whkd.exe && Start-Process whkd -WindowStyle hidden # if shell is pwsh / powershell
alt + shift + o : komorebic reload-configuration

App shortcuts - these require shell to be pwsh / powershell

The apps will be focused if open, or launched if not open

alt + f : if ($wshell.AppActivate('Firefox') -eq $False) { start firefox }

alt + b : if ($wshell.AppActivate('Chrome') -eq $False) { start chrome }

Focus windows

Output of komorebic check

No KOMOREBI_CONFIG_HOME detected, defaulting to C:\Users<user>

Looking for configuration files in C:\Users<user>

Found komorebi.json; this file can be passed to the start command with the --config flag

Found C:\Users<user>.config\whkdrc; key bindings will be loaded from here when whkd is started, and you can start it automatically using the --whkd flag

[LGUG2Z]

When the ghost tile is there, run "komorebic visible-windows" to get the information you need about it to add a rule ignoring it: https://lgug2z.github.io/komorebi/common-workflows/ignore-windows.html

Also for anyone having the same issues: temporary workaround I've been using for stuff I don't want to bother making special rules for is to switch to the window with alt + hjlk (or whatever) and then minimizing it with alt + m (or whatever).

It would be nice if the heuristics detected invisible windows though.
