Mesa bug thread

@All
Let's share all issues you find in one thread there.

Quote:

Check if you have used 32 or 16bit screenmodes (in current version 32bit ones only supported, will be fixed in next version). If that not helps, plz give me that:

1). you radeonrx or radeonhd version
2). graphics.library, kerenl and OS version
3). video card you use
4). post output of c:radeon_gpu_info
5). is it only glmark2, or also shader test cases

Thanks!

@kas1e

It doesn't get to screen to choose screenmode just error I posted on separate thread

1- RadeonHD-5.14
2- graphics lib-v54, OS4.1FE-Update 3, kickstart-54.57, Workbench-53.67
3- RadeonHD 7950

4-9.AmigaOS:> c:radeon_gpu_info
radeon_gpu_info_probe: FAIL device-facts status=ATOMBIOS_INVALID (32)
radeon_gpu_info_probe: FAIL exit=5

5- both

I mean workbench screenmode :) But not so matter because: ATOMBIOS_INVALID mean my ATOMBIOS parser fail on your card for some reassons.

RadeonHD 7950 its something like R280X, right ? And its should be Tahiti chipset, so it supported , just parser fails strangely on your card..

Can you plz send me a mail on kas1e@yandex.ru, so we can sort it privately ?

Thanks!

@kas1e

ok thanks email sent

@kas1e

I'm trying to compile a simple OpenGL app that opens a window using SDL2 and querying a couple of things using glGetString it fails on compile with the following error:

Quote:

I copied the mesa files to a fresh SDK install. I skipped the minigl stuff because of possible conflict issues. The test files work flawlessly so I know the mesa.library is installed correctly. Am I missing something?

Thank you,

Kevin

@kishigo
Current SDL2 you use didn't support mesa, but support only ogles2.library (so gl4es , warp3dnova, etc). To use mesa with SDL2 you need SDL2 which have support for it. I do not know how we should handle it in official SDL2 , this is up to Capehill, but in meantime you can use my SDL2_mesa.a (which you put to your SDK to the place where your current libSDL.a) placed then you use instead of -lSDL2 as -lSDL2_mesa. This version based on latest SDL2 from capehill, just instead of ogles2 mesa is used. There is: https://kas1e.mikendezign.com/aos4/mesa/libSDL2_mesa_2_32_10.zip. Of course you can rename it to libSDL2.a , and overwrite your current one, but then you will only able to use mesa since.

@kas1e

Thank you! I've downloaded it and will try it later today when I have time.

Are you planning a new version of MESA?

There are many new fixes between version Mesa 26.1.5/2026-07-15 and Mesa 26.2.1/2026-08-20
