When taking a screenshot with in-app keyboard command ALT+S i get a completely wrong output (see attached).

SDL Surface renderer is fine, so it's a problem of the OpenGL renderer

I couldn't replicate it on Windows, so it might be something specific to the Amiga platform.

Could you try to revert https://github.com/scummvm/scummvm/commit/bdd2fb61d1dd58c941888d6b3f95b75571e4d986 and see if this fixes the issue?

There are known issues with screenshots when using the OpenGL graphics mode. See bug #13767 and bug #13348. This could be the same issue or related to it.

Reverting didn't help, still the same issue.


It does look similar, so at least nothing I have to go manually hunting/bisecting for.
It happens as far back as 2.5.1 for me (I'm normally using a third party app to take screenshots)

Thank you for the heads up

@raziel- the issue with the alpha channel in screenshots when using the OpenGL renderer should be fixed, could you please try again on Amiga? Thanks
