Artifacts in DMA2D #1

Closed papadkostas closed 5 years ago

papadkostas commented 5 years ago

It is known that when the DMA2D is working we get artifacts on the screen. So i open this up if anyone's arround trying to find the issue together. I tried to disable DI cache and the artifacts are gone, but I get average 380ms for each frame. Also tried to used latest CMSIS and HAL drivers but the issue remains.
