imageFence seems to have no purpose. And some of the comments seem to be out of date / misleading. More importantly, do the command buffer completion wait before the acquireNextImage. Otherwise frame.imageSem may have wait operations pending if the queueSubmit did not get to wait on it yet. The expectation is that this potential issue is what triggers the recent validation layer releases' enhanced synchronization checkers.
