Greetings,
I see some artifacts on random 4k videos: https://photos.app.goo.gl/NVArgB5WteUKa4bY8
A media file info that causes artifacts: https://paste.kodi.tv/igiwururaj
The weird thing is the following video samples looks good, no artifacts or glitches even tho they are more resource consuming than previous sample, I believe:
jellyfish-120-mbps-4k-uhd-hevc-10bit, jellyfish-400-mbps-4k-uhd-hevc-10bit .
By disabling hardware acceleration (VAAPI), I was able to get rid of artifacts, of course there're consequences: CPU load bumps up to 80% due to software decoding.
My setup:
Hardware:
Intel NUC / NUC7i5BNK / i5-7260U
16+16 GiB DDR4 2133 MHz
IO Stats when the problematic video is playing:
avg-cpu: %user %nice %system %iowait %steal %idle
5.50 0.00 3.50 0.25 0.00 90.75
Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn

nvme0n1p1 0.00 0.00 0.00 0 0
nvme0n1p2 0.00 0.00 0.00 0 0
sda 46.00 11776.00 0.00 11776 0
loop0 0.00 0.00 0.00 0 0
Kodi log: https://paste.kodi.tv/owowonuteq.kodi
dmesg: https://paste.kodi.tv/qacilaxefu
Will appreciate any help
