When I am typing I have text characters turn black or whole lines of text turn black. This happens on all sorts of websites and occasionally within programs themselves. I also have issues where text disappears in Browser tabs.
I have been trying to figure exactly the cause of this, but I am not having any luck. I notice this with both Firefox and Chrome.
I am attaching a screen grab for reference and any system update have been completed.
I have been having the same problem since last month. It started happening after a Windows 10 update, and unfortunately it didn't create a restore point even though it was a WINDOWS update (go figure). According to MS, the fix is to do a clean boot, but that is only temporary fix if it works at all. Here is link to the conversation on the MS forum:
I found this issue posted on some other forums, but it appears to be a growing problem and nobody has any fix.
