Problems with new HTPC on Debian 12
cochinada:
I'm sorry to say but I'm totally p*ssed now. >:(
I've installed Ubuntu 24.04.2 LTS and the issue with the artifact remains!!!
So, what now?
I've asked ChatGPT for help "This same video plays perfectly fine in VLC as I told you, on the same computer. It is just when JRiver is playing it that I see those." and...
ChatGPT said:
Thanks — that’s a really important clue.
If VLC plays it perfectly on the same system, then we can confidently say: ✅ Your drivers, hardware, and codecs are fine.
❌ The issue is clearly in how JRiver is handling video playback on Linux, either with hardware acceleration or its rendering path.
🔍 What this likely means:
JRiver on Linux still isn't as mature or optimized as its Windows counterpart, especially when it comes to:
Video rendering backends (OpenGL, Vulkan, etc.)
Hardware acceleration layers (VAAPI, VDPAU, DRM/GBM)
Tone mapping / HDR handling
Frame timing / sync

Found it, uncheck this:
Options > Video > JRVR Settings > Advanced > Debugging: Visualize Tonemapping LUT
It's showing the HDR tone map that is being applied for HDR files :)

Well done!!! Are these settings OK now?
In the meanwhile I've found some bug with the display of some windows that randomly appear so small than one needs a magnifier to see them.
Check this out:
Believe it or not, that "thing" is the window with the settings.
I hope this shows better what I'm trying to say:

The thing with dialogs and windows appearing shrunk/small is a known MC issue if you're using the Wayland session of your Linux distro (which is the default now for many distros including Ubuntu). MC only supports X11 and doesn't support Wayland however it can run on Wayland thanks to XWayland, though it has issues like this. If you can live with it and know how to resize the shrunk windows, it's fine. But if it bothers you too much you can 'fix' it by switching to Ubuntu's X11 session.
To switch to the X11 session, all you have to do is log out. Then on the login screen where it asks you to input your password click on the gear on the bottom right and select Ubuntu on Xorg and log in normally. It should be using the X11 session then though you can always switch back to Wayland by repeating the steps and switching from Ubuntu on Xorg to Ubuntu. You can always verify if you're using X11 or Wayland by opening the Settings app and going to the System section then About then System Details. It'll popup a window with information including what windowing system you're using (X11 or Wayland).
Personally, I use the Wayland session (since X11 AKA Xorg Server is basically dead now and Wayland is the future) and so I expect these issues with small dialogs when using MC. I do hope it's something that can somehow be fixed in MC (as I don't think MC supporting Wayland is happening anytime soon realistically) at some point in the future.

I've changed to X11 as you can see but the issue remains:
