I've seen this problem before and it's generally but not always a result of RAM issues on your Video Card. The reason you would see it happening more with apps like Premiere is because they push the GPU much harder than most others do.
Try running some render tests with DaVinci Resolve with it set to use CUDA and see what happens. It really pushes a Video Card, especially during playback and I've actually seen artifacting in the Rendered Videos from Resolve when a Video Card is failing.
