macro blocking/artifacts on some videos

  • Just wanted to ask if there is an issue of getting macroblocks/artifacts on certain hardware and not on other?

    Im using LibreELEC-S905.arm-8.2-8.2.3.1.img

    Only playing local files threw USB or HDD

    Im getting macroblocks/artifacts random, like 2-3 times per 5 minutes, hardware: android box T95M, S905X, 2gb ram.

    Never on 1080p 23.976 hz, always on 1080i 29.97hz ......

    So far on 3 videos, one from what I did see did not suffer from this....

    The videos that are affected are M2TS or MKV or ISO, so it doesent matter what type of format..

    Ive noticed my resolution is not present to chose in LE setting, my TV is a LED 32" with 1366x768 pixels, so I choose 1080p in setting...

    Ive tried all kind of fps setting, Ive tried : adjust display refresh rate all setting, STILL SE SAME....

    Tried different usb drives, different HDD:s, different usb ports, different HDMI cables, STILL THE SAME....<X

    Then I decided to try my Venz V10 android box, S905 , 1gb ram, (used the same setting in this one as the other one, same 1080p setting and so on)

    So far no problems, so it seems this one is working...:huh:

    My question is: Could it be some less good hardware in the T95M box that is causing this? compared to my Venz V10 android box

    Because the only thing that is changed is swapping Android boxes, other is same: LE version, same cables, same TV, same settings, same usb stick wich the videos are in..

    At first I thought it had something to do with resolution, but both boxes cant find my TV resolution so Im running 1080p on both, no difference in this matter.

    The strange thing is it never happens with 1080P 23.976 videos only on 1080i 29.97hz

    Any tips to try? or is my T95M box bad ?
