I starting having an issue a few days ago that I hope someone can help me with. Sometimes when using the trackpad on the touch cover I experience some serious lag. The mouse pointer will continue to move across the screen at a slow speed then quickly jump to wherever it would've made it to in that timeframe at normal speed. The issue is extremely annoying. I've tried uninstalling and reinstalling the trackpad drivers. Rebooting the computer and removing some recently installed programs, but still the lag issue persists. Thank you to anyone who can help.
