Hi,
Sort of sounds like might have has been fixed with [1].
The change itself was integrated in weston 12, so you'd need to pick
that version to test it out. Debian has only only weston 11 in
experimental so you would need to either grab 12.0 branch from git, or get
it from [2]. In both case you'd have to compile it yourself. If you
manage to test it out and still see the issue, suggest to open a gitlab
ticket.
the related error is a little different. I am not changing any size, it
happens on HDMI plug and unplug. However, it may be related and the cause.
I am fixed to this Kernel, will be hard to get Weston 12 running. Any
idea for a work-around?
Thanks,
Martin

I guess I have an issue with XWayland (but maybe Weston / Linux). It is very
specific and I kindly ask for help.
I have a Java application running on:
XWayland 2:1.20.11-1+deb11u6, Weston 9.0.0-1, OpenJDK 11.0.18+10-1~deb11u1,
Debian 11, Kernel 5.10.52
My JFrame (Window) is set to:
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(this);
I can then see my interface on the full screen (in my case it is a TV and I
have CEC enabled in the Kernel). However, after I UNPLUG HDMI and then PLUG
HDMI again, my interface is gone (black screen). There is only one small 1x1
pixel left. It seems the size of the Window is changed by Java / XWayland /
(Weston). I am sure, that I am not changing it - I checked all resize
methods on JFrame.
When I restart my Java application, it is back again - so it is not an issue
of the OS (Linux) directly and also - most probably - not Weston.
I also don't have this issue with a pure Wayland application (e.g. Weston
flower). Using only Wayland (without Java and XWayland) things work.
When I PLUG the HDMI there is NO java.awt.event.ComponentEvent
When I UNPLUG HDMI, I get the following java.awt.event.ComponentEvent:

Unfortunately I also don't know how to manipulate the size after I catched
this event. I tried to directly set the size back, but this did not work. I
think it may don't work because at this time HDMI is UNPLUGGED.
As I don't get any event when the HDMI is PLUGGED again, I also don't know
when to (try to) set the size back to "normal".
Thanks,
Martin
