I have an issue with some movies which I tried to watch with VLC (2.2.6) on Windows 7 64bit (Fully patched, Drivers are up to date from the Vendor Website). The issue is that those movies have a grey skin. However when I watch the same video on the same TFT screen with MPV (https://mpv.io/installation/) then the colors are ok. That looks like a bug to me, however this might also some kind of VLC limitation here. The issue is not caused by the Video Effects filter, as I didn´t touched that one. I also tried to re-install VLC and deleted everything. I also re-installed the whole PC (mostly because of the move from a HDD to SDD) which also didn´t solved the issue.
