If you are experiencing issues during a creative session where your mouse cursor gets cut off halfway through a click-and-drag action, it may be due to a failing left mouse button.
Initially, you may assume that the problem is caused by user error, such as releasing the button or not pressing it hard enough. However, if the issue persists, it is likely that the left mouse button is beginning to deteriorate.
There’s 3 options to fix this issue.
Personally went with option 1 and bought a new mouse. You may be a mouse enthusiast and change the mechanical switch. While software like Clickfix may help alleviate the issue in the short term, it is only a matter of time before the switch or the mouse needs to be replaced. Ultimately, the decision on how to address this issue will depend on personal preferences, skill level, and budget.
