Forza horizon 4 works perfectly fine on 6.3-8 with xorg (Nvidia or AMD)

I can finally give my phone a break now that Snap works on Linux.
Since several version ago, I have a regression with Proton Experimental with games that use mp4 files like Back4Blood or Borderlands 3..

Proton is missing proprietary video codecs. Use proton-ge-custom instead which is built with this codecsupport. Should run fine with it.

With PROTON NEXT (7.0-5), it works fine... SO it must be something bad with the experimental build.
