Problems with gpus on NetBSD current

[chris greek <chrisfromgreece%gmail.com@localhost>]

I have tried NetBSD current with joyent packages .
Seems that has problems even with my 100% compatible with NetBSD gpu
AMD Radeon HD8490 (caicos family) that works fantastic on NetBSD 9.2
and even performs fast on firefox playing butter smooth 1080p 60fps
videos etc.

Also i tested some other gpus like the r7 240 which i'm having
problems even on 9.2
i tested r7 240 and my integrated gpu R7 both have some artifacts and
on some cases fails
to display text or icons on buttons , has artifacts when i open a menu
, and erases areas on every html5 games and online "apps"?

But i didn't expected i would have problems with my hd8490 on current .
Seems to have troubles with compositors where on 9.2 it works fine.

Anyway i felt that i had to report that.
Gpu support is a major issue.
NetBSD feels pretty fast and with nice performance even on old
machines that i have tried it in contrast with another BSD operating
systems that got popular lately and is slow as turtle and unstable
like a psycho.
