I agree that it is odd that "bad electricity" could be causing problems in a highly sensitive digital system like a GPU only to the point where minor but consistently similar graphical glitches are present (and not outright crashes), but since all the evidence and logic we have seems to suggest that it is (possibly, at least) the cause, we should at least attempt to investigate further, even if there is also logic to suggest that it is absurd.
To that end, does anyone who still follows this thread and has the problem have an opportunity to try using their system on a UPS vs not, or going to someone else's house who you know does not have the issue? If that does indeed fix it, we have an obligation to continue investigating that further, since it would be a very unexpected outcome, honestly. If it does not help, then we really should put the theory to bed, despite how much it seems to be the one and only common denominator of who does and does not have the problem.
