While loading a software it is occurring and after that with mouse movement this is increasing. when I place mouse on some item it is not in the pointer but elsewhere the dizzy dots are creating destortion. Plz Help me. How to get rid of this? I updated everything, reset the graphics card, changed the monitor but nothing improved. I can't upload screenshots here. if there is any way please tell me
