[gzdoom-g2.1.pre-1231] Problem with 2D enemies

[Atak_Snajpera]

I can't get rid of this annoying glitch on my Radeon 4850 (latest drivers). I've tried various options in OpenGL section and still nothing.

Does it happen with the latest development builds? (The one you're using is pretty old).

[Atak_Snajpera]

I've just tested 1665 build and result is exactly the same.

That's a driver bug. Looks like it doesn't properly invalidate buffer contents and reuses old data, even though it was overwritten.

You can try launching GZDoom with '-gl3' on the command line, which will disable any GL 4.x features and revert to immediate mode rendering.

[Atak_Snajpera]

Well It looks like I'm DOOMed for good. I've tried your switch and also tested older drivers (12.6 and 13.1) and still nothing.

How about the 1.8 builds?

[Atak_Snajpera]

Hurray! 1.8.10 Build works fine on my Radeon 4850 !

For reference, I have a 4850 on my Windows Server computer. It does not support GL4 at all, it will only do GL3 in GZDoom anyhow.
