Can you access the system over the network and
see if there is anything in the system log?
It sounds like the display stack has crashed, but
when the sound keeps playing the system is most
likely still responsive over network.
Thanks,
Christian.

What happens is this simple: after a few
minutes, about 6 or so, the entire content of
the screen stays still. In some minor
situations only the applications panel of KDE
Plasma.
If music is playing it continues playing,
so only graphics are hung. Yet in most cases
the power button won't shut down the computer,
as it usually does.
At least this is the case using kwin on
x11, and not on wayland. It only happens on
"radeon" and not on Intel or "radeonhd".
Correct, but a TV is intended for videos
only. That's why it implements only the
lower HDMI standard.
Interlaced transmits only halve the lines
with each frame, so a 60Hz mode effectively
either becomes a 30Hz mode, halving the
vertical resolution or adaptive motion
compensated which the know visual artifacts.
Depending on what the deinterlacing setting
on your TV is.
You could just add a progressive 1920x540@60
or 1920x1080@30 mode manually and would have
the same effect with probably better
quality. See https://de.wikipedia.org/wiki/Deinterlacing
for reference.
If you can give us some more information
what is happening when the system freeze we
could try to narrow this down, but we can't
spend much time on a very specific use case
in a driver which is in maintenance mode.

Christian.

24fps is intended for video only.
Anything interactive at 24fps, as just
moving the mouse around, is extremely
choppy.
No way anyone would prefer that
over an interlaced resolution or a
lower resolution. That is, by far, the
worst option.
Just try it on your screen, set it
to 24Hz or alike, and tell me your
experience. You can't even tell where
the mouse is going to go.
Interlaced
resolutions
are not used
any more on
modern
hardware, so
they
are not well
tested.
