MirAndroidPlatformClientFenceSync#
Classic fence-only synchronization without GL command buffer flushing.
MirAndroidPlatformServerBackpressure#
Allows redrawing to be skipped or not after a missed frame, similarly to SurfaceFlinger.
MirAndroidPlatformServerClearFbFence#
Framebuffer changes only continue after the fence has been successfully waited on.
MirAndroidPlatformServerEglSync#
Allow or avoid synchronization using EGL fencing primitives when drawing the screen.
Overrules existing launcher argument.
MirAndroidPlatformServerPartialUpdates#
Allow partial redraws to HWC-assigned server-side buffers.
