As of today I've noticed my trackpad not working correctly. Usually I can use the whole trackpad with no issues but when I've used it today I've noticed in some spots it works fast/normal and others it's really slow[almost like a start and stop motion]. Will I need to get a new trackpad to fix it/what could be causing the problem? I moved the speed of the trackpad up a little just to test it and I found that it still did the start and stop motion but it was a little faster as well. But then the spots acting normal were really fast.
