(some) Good news folks! I had a handful of win 8.1rt updates go through on my tablet yesterday, and I was hoping it fixed some things. While I still get graphical glitches in games, it's important to note that I no longer have to do a reset every time my screen times out! I've tested this in a variety of ways and cannot replicate the need for a system reset.
Please give the latest updates a go and report your findings!!
I installed the latest update and after it I have got one sleep of death. I didn't have any problems when I had the setting "never" for screen time out. This is quite annoying.
