Can't draw with Photoshop anymore

What it says on the tin and I'm sure you know. It sucks after more than two decades to leave your ever reliable program but my job is art and since this program can no longer be used to do that in any manner it's useless. Overall simple as this. I move something? Program automatically moves it somewhere else even if that was by single pixel. In the process it tears the image apart at the pixel and smears it. I make a perfect circle, one of the tools of course? Afterward the program moves it a single pixel and in the process tears the edges of it so it is no longer a circle. And so on no matter what. I can not turn in work like this for money or otherwise. It's that simple. My work will be rejected. It would be no different than trying to turn in a professional coloring job where you colored outside the lines but in the case you aren't but your brush is. Make some public announcement when your program is fixed please and thanks.
