Describe the bug
When I get a Windows Notification (e.g. from MS Teams) the popup gets handled like a full window. It occupies a whole window space (like a new windows would), but only fills the popup-size area in the top left corner.
After closing the popup the space remains empty and I can't fill it again. I have to restart komorebi for this to work again.

To Reproduce
Steps to reproduce the behavior:

1. Start Komorebi
2. Use your preferred tiling
3. Get Notification (In my case: Teams Notification)
4. Popup will be handled like a new window
5. After closin Popup, empty space won't get filled up again. It is treated like a window

Expected behavior
I think the popup should not be treated like a window at all and remain in the corner. If it is closed, the empty space should also disappear.

Screenshots and Videos

Operating System
Provide the output of systeminfo | grep "^OS Name\|^OS Version"

For example:

OS Name:                   Microsoft Windows 10 Pro
OS Version:                10.0.19045 N/A Build 19045

Thanks for the detailed report!

I recall a while ago some people were struggling specifically with Teams notifications, and after some trial and error these rules were added to the generated configuration.

Can you confirm that you seeing the behaviour above with these rules applied?

Hey, thanks for the quick response. Yes I do experience it with following content in my komorebi.generated.ps1.
this is a snippet from my config:

# Microsoft PowerPoint
komorebic.exe identify-border-overflow-application exe "POWERPNT.EXE"
komorebic.exe identify-layered-application exe "POWERPNT.EXE"

# Microsoft Teams
komorebic.exe identify-border-overflow-application exe "Teams.exe"
# Target Teams pop-up notification windows
komorebic.exe float-rule title "Microsoft Teams Notification"
# Target Teams call in progress windows
komorebic.exe float-rule title "Microsoft Teams Call"

# Microsoft Word
komorebic.exe identify-border-overflow-application exe "WINWORD.EXE"
komorebic.exe identify-layered-application exe "WINWORD.EXE"

This part was already inside the config. Is it possible, that the title is dependent on the System oder Teams language? I tried translating that to german as 'Microsoft Teams Benachrichtigung', which also did not work.
Maybe you have some tips for debugging this?

The next time that you are left with a ghost tile after a notification, could you share the output of komorebic state? It would be interesting to see the exact details (title/class/exe) of the window for which a ghost tile is being reserved.

Thanks for the tip with komorebic state, I found out, that my translation idea was correct, but the german version of teams uses a dash. So I had to rename the target window from 'Microsoft Teams Benachrichtigung' to 'Microsoft Teams-Benachrichtigung'.

My config looks now like this

# Microsoft Teams
komorebic.exe identify-border-overflow-application exe "Teams.exe"
# Target Teams pop-up notification windows
komorebic.exe float-rule title "Microsoft Teams-Benachrichtigung"
komorebic.exe float-rule title "Microsoft Teams Notification"
# Target Teams call in progress windows
komorebic.exe float-rule title "Microsoft Teams Call"

The problem more or less persists when having a teams call where I share my screen. I have this small window, which takes up a whole tile. But when te call closes there is no ghost tile, so I can live with that.

Thanks for the help!

One trick that I do with video conferencing windows (Zoom is also quite temperamental) is to toggle-float on them and then drag them around to somewhere on the screen until they are done, so that they don't take up more space than they need to.
