MESA --
Stemming from an issue of slow performance inside LXDE's file manager, the Raspberry Pi VC4 Gallium3D driver has received an optimization for better texture upload performance.

Broadcom developer Eric Anholt has cleared up an issue around the texture upload performance that should help "almost any Cairo vector graphics operation with its Xlib backend", as Eric acknowledges, this VC4 Gallium3D change should benefit a lot of Raspberry Pi users on this open-source driver stack.

The Mesa Git change notes that for one affected x11perf test the performance increased by around 50%.

More details on this VC4 texture upload performance improvement via Eric's developer blog.
