Description

Most appropriate sub-area of Processing 4?

I'm not sure

Processing version

4.5.2

Operating system

Linux mint 22.1 Xia

Bug description

I get the following error: "java.awt.IllegalComponentStateException: The frame is displayable".
​This happens on both my desktop and my laptop. It seems to be related to java.awt.Frame.setUndecorated being called while the frame is already visible.
​Steps to reproduce:
​Open Processing.
​Click on the "Java" mode button to switch to "Android".
​The error window pops up immediately.

Research direction

Reproduce the problem on Linux Mint with Processing 4.5.2 by switching from Java mode to Android mode. Trace the mode-switch path around java.awt.Frame.setUndecorated and verify that switching modes completes without the IllegalComponentStateException and displays the Android mode.
