Hm, as for D3D11 and the others, that's surprising, I'll try to figure it out.

For the Vulkan change, that one fixed the GE frame dumps, but then theres' more to it...

[hrydgard]

@sum2012 thanks for the bisects, by the way. can you grab a couple of GE dumps of the bad rendering?

[sum2012]

I have grabed 3 times.It is black screen.

Thanks! I'll take a look at them soon.

Just a test
Revert #18650 fix opengl,d3d9,d3d11,Vulkan

[hrydgard]

@sum2012 thanks, might do that for 1.17.1.

(But, it also will "unfix" the tokimeki bug with the weird bottom part of the screen in those framedumps, but better that than not being able to play, I guess...)

[sum2012]

@hrydgard No, it is still fix " the tokimeki bug with the weird bottom part of the screen.
Here is the the frame dump
