Kernel panics after HEVC encoding, frozen screens..


i have lots of weird issues on mac pro late 2013 since installing high sierra, , appear connected graphics cards or drivers (just 1st theory).

have 2x dell 5k displays attached through dual thunderbolt cables.
first issue had 1 of them consistently used 1 tb lane after booting, meaning 1 half of 5k image being stretched on entire screen- not nice @ all, got resolved through power down, unplug power, reboot.

next issue:
leaving machine doing something, displays went lowe saving mode, never turned on again afterwards.

next issue:
today during background file transfer, in order prevent aforementioned issue, turned power saving mode off , let screen saver on- happened screensaver froze! couldn’t move mouse anymore or somehow mac come showing moving image- force reboot.

next up:
encoded mov quicktime using hevc. @ end of encode got first ever kernel panic in 4 years!

encoded 1 hevc adobe media encoded , same thing happened!
files fine each time though.

strange!
