Malfunctioning codec

[KacsiGugu]

Hey!

Any idea how I can fix/reset my codec or what to do to fix the images of the videos?

All the movies is looks like the attachment.
The bsplayer version is the latest: 2.70.1080 Free
And all codecs installed with the codec manager.
My system is Windows 10 Pro N 64bit
Intel I7-6700
Nvidia GTX 970

Tested video:
Codec: MPEG-4 Video (XVID)
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Codec: MPEG-4 Video (DX50)
All three:
Decoded format: Planar 4:2:0 YUV

Thanks in advance

Edit:
I tried to uninstall all codecs in the manager and the video still plays in this buggy mode, so now the question is how can I find out what codec the bsplayer use, since I don't installed any codec packs...

Yeyyyy fixed:
"Internal Direct3D renderer (test)" not working properly, switching to
"Internal renderer overlay (default)" solved my problem.

Still no idea why D3D was selected.
