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

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
Small amounts of text:
$ driconf
Mesa 19.0.1 implementation error: Incomplete OpenGL ES 2.0 support.
