To reproduce, run the following on the metal branch using the (default) MTL pipeline:

1. Run the SwingInterop example:

java -jar apps/toys/EmbeddedSwing/dist/EmbeddedSwing.jar

2. Click on the blue folder icon labeled "Classical:

BUG: It will overwrite the folder with a copy of the tab pane that is above the folder

If you refresh the window it will repaint correctly.

This bug only happens on the MTL pipeline. If you run it on the ES2 pipeline you can see how it is supposed to look.
