Bug ID: 110318 Summary: Disabling ARB_fragment_shader causes implementation errors Product: Mesa Version: 19.0 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/i915 Assignee: dri-devel@lists.freedesktop.org Reporter: astrosnail@protonmail.com QA Contact: dri-devel@lists.freedesktop.org

Created attachment 143856 --> https://bugs.freedesktop.org/attachment.cgi?id=143856&action=edit 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
