When I start Isabelle2025-RC0 by, e.g.:

/opt/Isabelle2025-RC0/bin/isabelle jedit&

the initial window takes over the entire screen area. I consider this
behavior
to be intrusive and Isabelle2024 does not do this. Even if I "restore down"
using the window manager controls at the upper right of the title bar,
exit the program, and restart, it still does the same thing. I scanned
all the
options I could find and I don't see anything that would enable me to
change this.

System: Linux Mint 22 (Xorg).

Correction to my previous message (sorry):

The behavior observed is when running Isabelle on Ubuntu 22.04 under Xorg,
displayed remotely using Reminna -> xrdp on a system running Linux Mint 22,
also with Xorg. I have not tried it without the xrdp, but the behavior of
Isabelle2024 and Isabelle2025-RC0 is different even under this configuration.

This sounds like some odd window manager problem: it is a matter of OpenJDK to
do this correctly, but it often doesn't.

For Isabelle2025-RC1 there will be another update of jdk-21, which might
change the situation again.

In the meantime you may also try out https://www.nomachine.com instead of Xorg
/ RDP.
