It's happened to me, I haven't gotten a chance to test it.
My specs are a 6600K i5 (stock clock) and a XFX 270x.
Users with GPU's and CPU's both above and below mine are reporting the same issues to Discord and stating that the solution was to disable hardware acceleration.
That doesn't even make sense. If it's using hardware acceleration it shouldn't affecting it that way. If anything the clock rate should be going up since it's not idle. Anycase shit programming on their part I suppose.
