I honestly don't think it's splashtop that is the problem, like I described earlier it crashes only when in sleep, then when I wake up the device the info pops up telling me the display has stopped responding and has recovered. I think splashtop being blurry is the bad results of the display drivers not working properly.
Honestly, at this point I would a reset or refresh, I'm not seeing any of these issues you're seeing. I have some Outlook.exe and Facebook Modern UI App errors but not Video Card issues. If the reset doesn't fix it, I would setup an RMA.
I sent my device to Microsoft. But not because of the driver error, I had a scratch in the LCD digitizer and dead pixels. The driver problem usually fixed it self.
