Do a/v sync adjustments work for MC for Linux?

Jim, I've tried a few different X versions on Debian, but with no noticeable difference.  I've also tried running MC under wayland (via xwayalnd).  The desync seems to be pretty persistent in my testing.

Perhaps this is an issue that can get some love during MC28 development.

While I have your attention, let me ask you if you have this issue under X11:

On a freshly booted machine; JRiver Theater Mode scrolling is very fast and smooth.  Then, in anywhere from just 5 minutes, to hours, or even days later, with no rhyme nor reason, scrolling becomes as slow as molasses, moving in slow, giant, juttery chunks. During the issue, resource usage is practically nil.  My troubleshooting measures regarding this issue have been the same as my original post.   This does not happen in Wayland.

I don't have the slowness you describe in scrolling.  I generally see about the same performance in X11 and in wayland.  FWIW, MC always runs in X as far as I understand it, so it's just whether it's running in native X or in the xwayland compatibility layer.  I haven't really noticed any big changes in MCs behavior, but the only DE I run that has both wayland and X options is Gnome. XFCE is X only for now.

JimH:
I've asked Bob and Hendrik to take a look at this thread next week.  Thanks for the details.

Belarathon:
Thank you, kind sir!

As for a different X11, do you mean a different distro?  As far as X11,  I'm partial to KDE and I realize it's not supported, but at the rate Wayland is coming along under KDE development, it's practically a a bug-free, usable system.  That would make my X11 issue superfluous.  I just tend to flounder under Gnome.    :-[

Fedora 34 KDE will now default to Wayland if you have an AMD card; up until only recently Wayland would pretty much crash moments later if you had Nvidia.
OpenSuse Tumbleweed gives the option of pure Wayland, Wayland X or X11.  If you want it in Arch, you have to install a few extras to get a session.

Oh I know KDE has a wayland session, I just don't use KDE regularly at all was what I meant.  I meant that I don't see any slowdowns in X under Gnome or in Wayland under Gnome or in XFCE. 

I do see the a/v sync issues in all three though.
