Doubtful, since I used 2200G without issues. Only change was using amdgpu
due games being particularly slow.

By "reproducing video" I mean watching videos from either Youtube/Netflix
with Firefox or mpv for local files. But note that I've experienced at
least one lock up
without any video on screen (I don't remember if there was something paused
on the background).

Using mesa 18.3.4, and according to glxinfo DRM 3.30.0, LLVM 7.0.1. With
vulkan, vdpau and va drivers on the same version. I gave up and removed
any and every instance of the rocm package, since the module couldn't
compile on the kernel.

Another detail about the lock up: the screen doesn't freeze but no
signal is emitted,
so my monitor goes to sleep.

Upgraded to mesa 19.0.1 and llvm 8.0.0, although I didn't see anything
relevant on the
changelogs that could affect my experience.
