Bug #7326824 When a layer is taken out of the cache and initialized it gets cleared to prepare it for future rendering. This triggers the following sequence of operations: glBindFramebuffer(layer.fbo) attach texture storage to FBO glClear() glBindFramebuffer(defaultFbo) The clear forces a resolve on tilers which stalls the CPU for a little while, thus producing jank during animations. This change moves the clear to the next frame when we know we will have to execute a resolve anyway. Change-Id: Ic1939c25df20ed65a4c48dc81ee549b2cd8b6ec3
