I have some issues with VNAV in 0.991 as well. I took off from UUEE, armed LNAV and VNAV and everything went well until it started descending for landing at LTAI.
As you can see in the image below, i was supposed to be above 17000 ft at the next waypoint (AI730) but the altimeter already indicates 14600 before reaching the waypoint.
VNAV was in control all the time, i didn't disconnect it or modify anything in the FMC. The deviation scale was disappearing from time to time, so that's why you can't see it in the screenshot.
