Xperia XZ Premuim laggy video playback after the latest update android 8.0

I've purchased my XZ Premium 2 months ago, i had no problems with it so far great performance, incredible HDR screen, with Android 7.1 nougat on board, and updated it to Android 8.0 oreo the performance got even better. but i noticed a problem after receiving a small update in January 2018, in playbacking some videos on Sony's video app, the issue is whenever i play an mkv video formats the video gets laggy , first i thought the phone doesn't support this format or something like that, but when i tried to to play another regular mkv videos the same issue occur, I got frustrated then i tried to play the movies that I watched month ago it had the same issue, before it was playing fine now it's laggy, i was like "what is going on", I've lots of videos with different formats and resolutions, my XZ Premium can play 4K and 4K HDR content h264 and h265 codecs just fine, but when playing some 1080p video that is mkv / wbem format h264 or h265 the video gets laggy, even playing 720p videos, the problem don't occur with mp4 files only on mkv videos, it's so annoying. 

Imagine the phone can run 4k with no problems but lags when playing 720p videos, lol what  is going with this phone really.

My old Xperia Z with Android 4.4.4 kitkat can run the video without lags but my new XZ Premium lags, lol this new update totally ruined my new phone for good, I'm a big fan of Sony Xperia phones my first Android phone was an Xperia and the last phone I've purchased is an Xperia.

Plus: my friend had the same problem on his Xperia Z5 Premium, when he updated his phone from Android 6.0 (marshmallow) to Android 7.0 (nougat), I downgraded it to 6.0 and the problem  gone, i really wanna know why is this happening with the new Xperia updates.

Here is a video sample of the issue playing a 720p movie from 2004, lol.

Same, it really bad.

Must be software issue but the question is why they don't tend to fix it?
