Hi,

Loch runs fine on a Debian + KDE machine with this configuration:

1) no xwaylandvideobridge installed
2) inxi -G output:

I did not pursue this during the holidays.  Now that Therion 6.3.3 is
out, it is probably time to dig into it a bit deeper.

I downloaded Therion 6.3.3 from the git repository, compiled and
installed it.  No errors, that all went very smoothly.

Loch still does not run in a Wayland session.  It gives a segmentation
error and dumps core within about 2 seconds of launching.

I tried it on three different machines.  They all have the same basic
configuration.  All three fail in the same way.

SCINU reports that Loch works in a Wayland session running on Debian
Testing. I am on Fedora 41. Something is different, but I have no idea
what it is.  Could it be a different version of xwayland?

A bit more information about my system:

This system is a Dell Optiplex. The other two systems are a Dell laptop
and a Lenovo laptop.  All are running Intel i915 displays.
