That one works, also with modesetting driver.

Regarding your question if modesetting driver is any beneficial: I'd say generally not, as it doesn't offer every feature of the xf86 DDX driver. But it can be sufficient in many cases, and I also just found a bug with xf86 driver + amdgpu.dc=1 causing stutter in mpv. So I'm lucky to have modesetting as a fallback in the meantime.
