If you prefer to stay on LE10 here's a first LE10 testbuild with 10/12bit video output and deinterlace patches (plus lots of other fixes, too):

It would be great to get some feedback on the LE10 testbuild as well, initial testing here looked good, but we'd like to have some more positive confirmation that things work as expected before adding the backport patches to official LE10 releases.
I Just updated from 10.0.1 to this version, and it's great! I had many problems/bugs with the 10.0.1 that I considered switching back to x86. But it's the first day and so far so good @4K60 and HDR. x264 also works now. HDR seems a lot better also. Thanks for the release.
