We have different approach on how flip is considered being complete. We are waiting for vblank on DSB and generate interrupt when it happens and this interrupt is considered as indication of completion -> we definitely do not want to skip vblank wait. Also not skipping scanline wait shouldn't cause any problems if we are in DEEP_SLEEP PIPEDSL register is returning 0 -> evasion does nothing and if we are not in DEEP_SLEEP evasion works same way as without PSR.
