Windows 8 Problems

[Xmishma]

I also ran into this problem. I obviously don't know what triggered it for you but, in my case it happened when I connected my laptop to an external monitor. I went ahead and reconfigured my video driver and now works between my normal display and external display. Seeing as you have not posted with issues again for a few days I'm assuming you haven't had any trouble since.

For anyone having future issues with invisible characters, just make sure to check the video driver, especially if you do use dual/external monitors since Windows uses profiles to tell the difference between displays.

Hope this helps anyone in the future

EDIT: After looking around a little bit, when you install the generic video driver, if you have automatic updates setup, Windows will want to install the correct driver for the video. Seeing as some drivers are not loading up char models, you can change the windows update setting to "Check for updates, but let me choose whether to download and install". For anyone who doesn't know how to do this, right click start > system and click on Windows Update and then change settings.
