I'm hitting several other GL error conditions first: Mesa: User error: GL_INVALID_VALUE in glSampleMaski(index) Mesa: User error: GL_INVALID_ENUM in glFramebufferTextureLayer(target=0x1) Mesa: User error: GL_INVALID_ENUM in glDrawElementsInstanced(mode=8ca8) Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture Mesa: User error: GL_INVALID_ENUM in glBindRenderbufferEXT(target) glGetError = GL_INVALID_VALUE Try running the app with a debugging build of Mesa in gdb and setting a breakpoint on _mesa_error. program prints no errors when run on i965 (tested on haswell) For mi on Kabini env LIBGL_ALWAYS_SOFTWARE=true also gives same GL_INVALID_OPERATION... regression somewhere as it does not happen on 10.1 mesa, but it is in 10.2+ OK it happen once GLSL 3.30 is adveritised for llvmpipe: http://cgit.freedesktop.org/mesa/mesa/commit/?h=10.2&id=7380ce9bf68d6d9913b5901ea3a432b4dae0ba72 For radeon it is not there, likely once later on when that is also done for it. Both does not got this under env MESA_GLSL_VERSION_OVERRIDE=140 -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 113504 [details] simple sdl2 example If I try to blit from a multisample fbo I always get: GL_INVALID_OPERATION or with KHR_debug callback: GL_INVALID_OPERATION in glBlitFramebufferEXT(bad src/dst multisample pixel formats) This even happens when the target fbo has the same sample count. glxinfo |grep OpenGL OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD PITCAIRN OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.0-devel (git-3f1e128 2015-02-13 trusty-oibaf-ppa) OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.6.0-devel (git-3f1e128 2015-02-13 trusty-oibaf-ppa) OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.6.0-devel (git-3f1e128 2015-02-13 trusty-oibaf-ppa) OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: uname -a Linux c01 3.19.0 #1 SMP Sat Feb 14 23:33:44 CET 2015 x86_64 x86_64 x86_64 GNU/Linux
