Thank you! Yes, this problem with artifacts - bad screen is observed in DragonFly BSD only with "intel" video-driver, but with "vesa" driver all OK!
My hardware: Intel NUC5PPYH: CPU Intel N3700 Intel HD Graphics. On FreeBSD video-driver also "vesa" besause "intel" driver for Braswell/ CherryView in not ported for FreeBSD yet. Is it issue of bug intel video-driver? Workaround: to use "vesa" is good for common working on PC, but in case YouTube video this is poor quality of video. 17.06.2016, 11:08, "Sepherosa Ziehau" <[email protected]>: > On Fri, Jun 17, 2016 at 11:18 AM, Dmitry Postolov <[email protected]> wrote: >> Hi to all!
