After some time, my graphics cards will not play x265 video on any player eexcept for sound

It takes a long time, but sometimes the screen will have a kind of slight glitch that's hard to describe and then reading x265/HEVC videos on any player.

a couple weeks ago I that same desktop with the same 2 cards connected with Crossfire and I had to be in win7 for a week and nope, everything's alright, hadn't been there in a while and had tons of updates and updates for the cards drivers as well. That glitch never happened while in win7, I find that very strange, it does rule out the card being broken though.

I don't get it at all here and I hate rebooting for a reason like this.

Yep, a reboot is necessary after mining monero for me, it will start with small glitches when starting a video to not being able to play x265 video until I reboot that machine and its 2 graphics cards. I guess it's a solved issue although it isn't really solved. Better than anything physical breaking down.

Sounds like overheating to me, esp. if it happens after bitcoin mining. Post the text results of inxi -Fxz from the terminal.
