After upgrading my system from 1.4 branch to next, mesa intel acceleration stopped working.

Starting alacritty shows:
libEGL warning: DRI2: failed to authenticate
Error: There was an error initializing the shaders: Failed compiling shader: 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, and 1.20
