Description

Created attachment 143856 Full glxinfo output

When I disable ARB_fragment_shader support, various applications error with "Mesa 19.0.1 implementation error: Incomplete OpenGL ES 2.0 support." Deleting ~/.drirc recovers from the error.

Steps to reproduce:

1. Run driconf
2. Uncheck "Enable limited ARB_fragment_shader support on 915/945."

Actual results: driconf will error. glxinfo will segfault when it reaches OpenGL ES info, with a null version string. mpv with --opengl-es=yes will error with a null version string. Many others probably apply. All of them print the following: Mesa 19.0.1 implementation error: Incomplete OpenGL ES 2.0 support. Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa

Expected results: The applications shouldn't be allowed to use OpenGL ES 2.0, given the disabled fragment shader support.

Versions etc: Arch Linux x86_64 mesa 19.0.1-2 driconf 0.9.1-14 mesa-demos 8.4.0-1
