Correcting Cursor Drift from System Sensitivity and UI Scale

High system mouse sensitivity and customized Minecraft UI scale settings can sometimes cause cursor movement calculations to land off-center. You can calibrate the mod to accommodate your specific display scaling.

Identifying Cursor Inaccuracies

Before adjusting settings, check how your current environment affects pointer movement:

1. Open your video settings in Minecraft and note your current GUI Scale setting.

2. Open a large interface, such as a double chest or crafting table.

3. Note whether the pointer consistently falls short of the interface midpoint or overshoots past the middle.

Applying a Calibration Scaling Value

To align cursor movement with your sensitivity and UI scale:

1. Exit Minecraft to edit your launcher profile.

2. In your launcher's Java/JVM argument settings, add or update:

-DcursorMoveScalingValue=<value>

3. Input an adjusted scaling value to balance how far the cursor travels across your display resolution.

4. Save your profile and restart Minecraft.

5. Test opening different interfaces—including the inventory, furnace, and chests—to ensure the cursor lands squarely in the center across all screens.

If you later change your desktop mouse sensitivity, system DPI scaling, or in-game GUI scale, revisit this argument to keep cursor placement properly aligned.
