From 6c694b6f0bd8c6ca4552d70ee3a538d51917337e Mon Sep 17 00:00:00 2001 From: Vojtech Bocek Date: Thu, 6 Feb 2014 20:36:25 +0100 Subject: Disable alpha blending for non-transparent bitmaps * The difference isn't as big as there are not many big non-transparent bitmaps in TWRP, on install screen on flo it is about 5-10ms better. Only place where the difference is noticable is keyboard, which is pretty big non-transparent bitmap, where it speeds up the render by ~40ms on flo.
