Hello Iohannes,
I compile the latest Git, and I experience trouble.
The render is not working : the window created by Gem did not update. The windows is not black, but is composed by whatever was on the screen before it's creation.
It look like the "1" is not receive by gemwin : gemhead did not output anything.
Investigating a bit:
in the "gemwin" abstraction, bangs are send to gemdefaultwindows, but gemdefaultwidows did not output anything.
(the default windows id : gemglxwindow)
(ubuntu mate 22.04 computer)
cheers
