GUI breaks when the size is changed to the minimum

[Kokecena]

As the title says the GUI starts to break, it is fixed when it is maximized but if you do the same thing again it happens again, I thought it was something in my application, but it also happens in the demo application, this does not happen with the base look and feel
My application:

20231124_020101.mp4

In the demo application:

20231124_020511.mp4

Maybe this has nothing to do with it, or maybe it does, but I don't know if the error is reported in the jdk bug system, when there is an application that overlays the java application the same effect begins to happen, I made sure not to have the MSI Afterburner or another application that overlaps.

I'm on Windows 11
Java version 17.0.6, BellSoft.

Thanks for reporting and for the videos.

Looks similar to: #700 (comment)

Was not able to reproduce it by manually resizing window to minimum size, but invoking frame.setSize(0,0) and manually increasing window size shows this effect each time.

Turns out that invoking following line from FlatRootLayout.invalidateLayout() causes the problem:

FlatLaf/flatlaf-core/src/main/java/com/formdev/flatlaf/ui/FlatTitlePane.java

Line 598 in ec76737

repaint();

Very strange that a simple repaint has this effect. 😕
