Message "Couldn't get HWND of window" in the log

Describe the bug
Sometimes during startup I see the error message below (or similar, same error but different classes). I'm just reporting it since it's marked as "SEVERE" but I'm not really noticing any issue with the UI and the application seems to be working just fine. Any idea what could cause it?

[25/05/2022, 12:01] [SEVERE] Couldn't get HWND of window (errorCode =-2141387734).javax.swing.JFrame[frame0,0,0,136x39,invalid,hidden,layout=java.awt.BorderLayout,title=,resizable,normal,defaultCloseOperation=HIDE_ON_CLOSE,rootPane=javax.swing.JRootPane[,0,0,0x0,invalid,layout=com.github.weisj.darklaf.platform.decorations.NativeDecorationsRootLayout,alignmentX=0.0,alignmentY=0.0,border=com.github.weisj.darklaf.ui.rootpane.DarkRootPaneBorder@2109da6a,flags=16777673,maximumSize=,minimumSize=,preferredSize=],rootPaneCheckingEnabled=true] [at com.github.weisj.darklaf.platform.windows.PointerUtil]

To Reproduce
I couldn't find a way to consistently reproduce the issue

Additional Information:

• OS Windows 10 21H2 (build 19044)
• Darklaf Version: 3.0.0

This actually looks like the report is a fluke. One codepath assumed all pointers < 0 are invalid. All other locations don't really core for negative pointers and work like expected (which is why you don't see any noticable difference).
Notably it does have a small visual impact right now in that if this happens with a popup menu then it won't actually have a shadow.
The error should be gone with the next version :) Thank you for reporting it

Great, thanks!

Version 3.0.1 has been released and should fix this.
