Selur's Little Message Board

I'm new here, obviously... but I need to ask some Q's regarding x265 encoding. I'm quite a seasoned encoder in x264 and I'm new exploring x265. 

So the situation is like this:

I was hardsubbing a subtitle file. It will work 100% right when the end product is x264. But when I tried to do it on x265, it goes bonkers and the end product was a messed up mosaic 

I'll attach a SS for reference.


Hahaha, like that. For those who will ask for what settings I've used, it's the standard slow preset.
Can somebody tell me why does this problem occurs? Thx in advance, good sirs/madames 



Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

Looks like a color space handling problem to me.
Without a debug output of the processing that's all I can say.
