Picture of the corruption when rightclicking in websites in chromium

There is a graphical garbage in the dropdown menu when right clicking any
plasma application, tooltips in any plasma application, it flashes very briefly
and is very partial regardless if I move the mouse cursor.

Same with chromium, but it happens more often and is more severe when
rightclicking inside a website. It doesn't disappear in this case until you
move the mouse cursor anywhere over the dropdown menu, if I right click the ui
itself in chromium(bookmarks bar) it flashes very briefly and is very partial
regardless if I move the mouse cursor over the dropdown menu.

It sometimes happen very briefly across the whole window when opening a new
window for Gwenview.

This started to happen after upgrading from kernel 4.8.13 to 4.9.6, it still
happens in 4.10.0. Different mesa version makes no difference.

The example shown in the image is easily reproducible for me by just right
clicking over and over and it will appear.

I can't seem to reproduce this on my Tonga.

Was it really only the kernel that made the difference? No updates for kwin /
Mesa / xf86-video-amdgpu / xserver / Mesa / ... in the meantime? What kwin
compositor settings are you using?

If it's really only the kernel, can you bisect between 4.8.13 and 4.9.6?

I tested all the way to back to kwin 5.7.5, issue still appears, tested mesa
from git, 13.0, 17.0 issue still persist. Xserver 1.19 and the latest
xf86-video-amdgpu has been used long before this issue appeared. 
Tried different kwin compositor settings, no change either.
The only thing that helps is to downgrade to kernel 4.8.13.

I don't know how to bisect to be honest.

No. I applied it to 4.9.11, running the firmware files you suggested to try.

The issue became even more prevelant when upgrading from kernel 4.10.2 to
4.10.3.
