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.
