    I suffer from the same problem. I believe I can shed a little more light on it:

    While the problem persisted in all of the OE6 versions, it was finally gone in OE7 betas (6.95.x). I don't remember for sure about beta 1 or 2, but it worked 100% in 6.95.3.

    Then, Libreelec 7.0.x reintroduced the problem for me. So something must have changed there. I hope that helps you track down the cause.

    I would suggest trying the latest LibreELEC x86 test build from this thread: LibreELEC Testbuilds for x86_64 (Kodi 17.0) - these builds are more bleeding edge than 7.90.003.

    Once you have confirmed you still have a problem with VC1 material, post a full debug log after playing one of your VC1 movies - enable debug logging, reboot, play your movie, then "cat /storage/.kodi/temp/kodi.log | pastebinit" and paste the link in the test builds thread with a detailed explanation of the problem. One of the Kodi VideoPlayer developers will hopefully then be able to suggest a solution, which will be to post a bug on freedesktops.org, wait for AMD to fix their driver, or if you're lucky there will be a bug fix in VideoPlayer.
