* package version: mesa 18.3.1-1

Description:
Since upgrading to Mesa 18.3, I'm experiencing temporary freezes in 3D software and games. In particular, the Godot engine seems to be affected, and it looks like it happens on shader compilation (OpenGL 3). It makes affected software unresponsive, sometimes for minutes. Other users have reported the same behaviour, as can be seen in the following bug reports:

https://github.com/godotengine/godot/issues/24340
https://github.com/godotengine/godot/issues/24362

Godot developers say that this is not a Godot bug and that "both Fedora and Debian were hit by a GCC bug when building Mesa 18.2.3 a month ago against latest GCC."
This task depends upon

Here's a related bug report for Manjaro Linux, apparently describing the same issue:
