Youtube videos lags/stuttering in any browser with any crimson driver

It so simple and common feature, accelerate videos with video card, but crimson with amd cards can't do it right way.
I posted here and reported to amd feedback form that problems, seems no one care.
Found post from 2016 with that problem here it is - The driver version 16.12 on Youtube lagging in full screen mode.
Solution - turn off hardware acceleration. Nice! I have video graphic accelerator and I must use software CPU render to watch youtube videos in 2017?!, yes, it helped, it's ok on AMD-FX 8350 where 1080 video using about 30% usage, and not ok on athlon x4 where it using 60% of cpu! Also "Nice" energy effectivity on FX what 125Wt TPD! On versions 17.2+ all videos have vsync off effect/choppy, now it just lags.
I tried latest chromium 63, it can't even use acceleration on amd, it enabled but not used, gpu stay at 300/150mhz and cpu usage high. It's clearly driver problem, when it's fixed?
