Test the mouse on a different computer to see if it works correctly. If it doesn't, the issue may be with the mouse itself.
Outdated or incompatible mouse drivers can cause cursor issues. Visit the manufacturer's website to download and install the latest drivers for your specific mouse model.
Go to Settings > Devices > Mouse and check your mouse settings. You can adjust sensitivity, scrolling behavior, and other settings to see if it resolves the problem. Adjust the slider labelled Mouse pointer speed. Moving it left will slow the cursor down, while moving it right will speed it up. Adjust it, moving your mouse between adjustments, until you find the right speed for you.
