Hi, I’m encountering an issue where using fragment shader interlock is almost like it doesn’t work on RTX GPU driver, while the same code with ARB_fragment_shader_interlock enabled works perfectly on GTX GPU drivers and Intel drivers.
The problem is flickering black texels running around at the bottom right of the screen, that’s where I use shader interlock to do limited programmable blending, but it doesn’t seems to function properly on newest RTX GPU driver, while on the given driver on 1050ti below, and intel drivers, it seems to work properly.
Here is the gif of what happens (RTX 2070 SUPER driver 435.80)
And here is what I expected (running on a GTX 1050ti driver 430.86, GTX 1070 driver 435.27 also works):
Reproduce VS solution and executable (in x64 folder):
I’m not sure if this is a regress or not, or only on RTX driver, or it’s our fault. Anyway, I would appreciate help, thanks!
