Makes using my mouse on any sort of dark background impossible lol. What I dont' understand is the issue getting fixed should keep it from occuring in further driver updates, so why does it seem to pop back up from time to time? Some weird code for the cursor needed or something?
Now, given I'm techincally running dual-displays (due to my little 5" monitoring screen in my case window) and I've heard that it's only an issue with dual-display systems. Any other multi-monitor users get the same issue?? (Sapphire Nitro+ 470 8gb card w/samsung 2000mhz RAM btw) I'm hoping someone has a fix that doesn't require a PC restart since sometimes it happens within minutes of a restart, other times it's a whole day before it happens.
(Also note, my PC is on 24/7... Is that bad?)
Somehow, in some way, the cursor memory on the GPU is being overwritten with junk data. Most likely, it's just a single byte or word (an off-by-one error) in some pointer arithmetic somewhere in some entirely unrelated part of the driver. A hardware-level memory guard would prevent this (or make it easier to find), but I doubt that's worth the effort.
Someone will discover the fix on accident and not even know they fixed it - just noticed an off-by-one error, fixed it, didn't notice anything wrong, and moved on... and then it'll be fixed.
