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

<< < (3/3)

Belarathon:
After  a year searching the interwebs, I have found the solution for both a/v sync issues and choppy, juttery scrolling problems for X11 under KDE:
https://bugs.kde.org/show_bug.cgi?id=397850

The proposed workaround solves a host of other performance issues with KDE under X11.  Developers are aware of the bug, but have apparently chosen not to address the issue.  Subsequently, the issue exists to this very day on the most recent Plasma with all updates.

The workaround involves  disabling triple buffer detection in KWIN:

export KWIN_TRIPLE_BUFFER=0

Likewise, if you have an Nvidia card, disable triple buffering in xorg.conf:

     Option         "TripleBuffer" "0"

You'll notice that this is completely contrary to common wisdom across the internet.

Latency is now practically nil, my a/v sync is spot on, and my KDE "feel" of performance and has increased by orders of magnitude.

 Thinking my problems were an Nvidia issue, I switched to an AMD card - same issues!
 If you read the bug report, this issue also affects AMD cards.

Thanks very much for posting that.  I added it to the Weird and Wonderful thread (link in my signature).

Belarathon:
Thank you!
