Description

Game Name?

Any

Game ID?

Any

What's the problem? Describe what went wrong in few words.

OpenGL shows a black screen

What did you expect to happen instead?

Graphics

What steps will reproduce the problem?
1.Set graphics backend to OpenGL
2.Play a game

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

4.0-4654

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

I haven't tested every version but 4.0-4573 works

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 7 X64

AMD A8-4500M APU 1.9 GHZ

Raedon HD Graphics
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Likely an issue with your drivers.

There have been some updates to the OGL so it could possibly be a typo there.

Can you bisect down to the exact build where the behavior changed?

It got worse in 4.0-4618 though.

That makes too much sense to be a coincidence.

When you say it got worse, can you explain how it got worse? Did more games black screen, or did less graphics show?

Are you certain your drivers are fully updated?

I wonder if increasing the size of the VBO would help, or if your driver is expecting enabled vertex arrays. Unfortunately, I don't have access to an AMD APU. Would you happen to be willing to compile and test some changes, if I told you which files to change?

Less graphics shown. Yes my drivers automatically update.

Here's a Windows x64 build with some changes. Does it work any better?
