SFML 2.3: OpenGL extension SGIS_texture_edge_clamp unavailable
« on: May 11, 2015, 04:04:38 pm »
I upgraded from 2.2 to 2.3 and now I'm getting this console output:

OpenGL extension SGIS_texture_edge_clamp unavailable
Artifacts may occur along texture edges
Ensure that hardware acceleration is enabled if available

What does it mean?

Should I be concerned, and how do I fix it? Thanks!

The issue has always been there, you just never noticed it because of no warning.
However the issues has already been reported and the fix is getting merged soon. ;)

Actually, the issue was never there, because it was never an issue. :P The warning isn't supposed to apply in this case (extension supported under different name), and that's the current bug.

Just ignore the warning for now. The 2.3 release is a bit broken, but the patch release will be out shortly. If you absolutely need something functioning right now, you can stick to 2.2 for the time being.

Ah well, then I misunderstood you. ;)

Sorry to bring back this thread from dead but this issue seems to be persisting for me. I'm on Windows 7 with C/SFML 2.3.2 and an NVIDIA Quadro Mobile series card.

It looks like this was fixed here: https://github.com/SFML/SFML/pull/882
Was it not in 2.3.2 release? Should I open a new bug report?

What do you mean with C/SFML?
It is fixed in SFML 2.3.2, if you use a CSFML version that doesn't actually use SFML 2.3.2 then you'll still run into the issue. ;)

I mean I use SFML and CSFML 2.3.2 and I still have this issue.

EDIT:
My app depends on this 2 dlls which are downloaded from the official website. They are of version 2.3.2
Code: [Select]
$ ldd bunny.exe
        csfml-graphics-2.dll => /mingw64/bin/csfml-graphics-2.dll (0x68a40000)
        csfml-window-2.dll => /mingw64/bin/csfml-window-2.dll (0x6f840000)
        ...
        ...

And the output of the app is shown in the attachment.

EDIT: Tried it on another computer with an older Quadro Mobile GPU, on arch linux and this issue doesn't exist there. So it looks like a windows-only problem.

CSFML has not been updated to 2.3.2, as far as I remember. But you can easily recompile it.

Ah now I get. Ok thanks for the heads up. Indeed the website claims 2.3 not 2.3.2
