Short description of error
Certain (still reasonable) values cause the Sun Disc of the Sky Texture (Nishita) to be rendered as partially or fully black in Viewport Shading "Rendered" as well as the final Render. The bug only occurs when using GPU Compute
(maybe a driver bug?)Exact steps for others to reproduce the error
Assuming a new file:
Playing around with the parameters in Sun Size, Sun Elevation, Altitude and Air can change the size of the black area of the sun disc, e.g. Sun Size < 2.6° = fully black, Sun Size > 3.3° full white, every value in between causes a black area inside the disc as seen in the screenshot bellow:

Hi, I confirm that this issue exists on my system too:
Worked in: 3.1.0
Broken in: 3.3.0 alpha
Windows 10 Enterprise
Nvidia RTX 4000 (driver 472.88)

Added subscribers: @lichtwerk, @PratikPB2123
Can not confirm when rendering with CPU (tested in 3.3)
Peter is also able to repro so less likely a driver bug. @lichtwerk , can you confirm?
I just loaded the file on my Linux machine and was able to reproduce the issue with:
1a627d528cf9
ae2d2c936161
System Information:
Since the issue occurs on different OSes and driver versions I agree with @PratikPB2123, a faulty driver is unlikely.
