What's the problem? Describe what went wrong.

When shooting star bits in the middle of the screen with the OpenGL backend, the star bits will act normal. But when you shoot them near the edge of the screen they act like EFB access has been disabled. The same can be seen when looking at the sun at different angles in SMG. When looking straight at the sun, it acts normal but when the sun is at the top of the screen the effect doesn't work. Other backends are not affected by this.

Is the issue present in the latest development version?

Yes, 9804

Is the issue present in the latest stable version?

No.

If the issue isn't present in the latest stable version, which is the first broken version?

The issue was introduced in 5.0-9737.Probably in this commit: https://github.com/dolphin-emu/dolphin/pull/7838/commits/6bc4bfd26af96de8642e75bbf644722c44baeb7b

Pretty sure the issue is because OpenGL uses lower left as origin and somewhere in the framebuffermanager, that isn't accounted for/not correctly used.
