Did a fresh installation.
The buffer trouble with hevc is still there and the solution works:
echo 16 > /sys/module/amvdec_h265/parameters/dynamic_buf_num_margin
In audio setting, I had to lower the thresold from 2 to 0 or I had some audio troubles with some files.
Tvh client feels faster
There's fewer info on files when using 'o' or info. Feels like every major kodi update strips more and more info on those screens. I do not like that trend as you have less data for debugging or distro comparison.
I do not like the overall look/feel/ergonomy. But I can't complain too much as this is an early version.
