I'm one of the few owners of the Sony Tap 11 (SVT1121) tablet computer, and after upgrading to Windows 10, YouTube and other videos were garbled during playback.
This is a known issue from Sony, and while they didn't offer any solutions, there's actually a simple fix for this:
Start -> type "VAIO Control Center" -> click on VAIO Control Center
In the control center, select Image Quality, then under "X-Reality for Mobile", toggle the switch to "Off".
This may also help owners of the Tap 21, although it's untested there since I don't think anyone ever bought one of those...
