1292326 - Disable layers acceleration by default on Linux when using a Mesa software GL implementation

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Andrew Comminos [:acomminos]]

When layers acceleration is enabled by default on Linux, we don't want to accelerate with LLVMPipe or swrast- performance is quite a bit poorer than our basic composition pipeline, especially with a low number of cores.

This is only a default; we'll force enable acceleration with LLVMPipe on the test infrastructure using layers.acceleration.force-enabled.
