From 3a1da60267cd397e466f7ceef0432cea41122590 Mon Sep 17 00:00:00 2001 From: Denis 'GNUtoo' Carikli Date: Thu, 2 Jan 2020 13:53:39 +0100 Subject: Use LLVMpipe by default Using libagl for everything had the side effect of making it impossible to use applications like IceCatMobile, as libagl OpenGL implementation was not complete enough. Using LLVMpipe fixes that. Using LLVMpipe for everything has the side effect of making some system components like SurfaceFlinger way slower. As we have patched the EGL loader to enable to override the default OpenGL implementation for specific binaries, and that we used that to switch the affected system components back to libagl, we can now switch to LLVMpipe.
