- Product
- Microsoft OneNote
- Device & OS
- Surface Pro 8 / Windows
- Scenario
- Using the stylus to select notes with the lasso tool in Microsoft OneNote.
- Observed behavior
- OneNote lags significantly and the lasso selection tool fails to work properly. This may be caused by a corrupted notebook or interfering background processes.
Before beginning troubleshooting, make sure your Surface Pro 8 has all recent Windows updates installed and that your stylus pen is fully charged and paired correctly.
Test with a New OneNote Notebook
Determine if the lasso selection bug is isolated to a corrupted notebook by creating and testing a brand-new one.
Launch the Microsoft OneNote application on your Surface Pro 8.
Click on the 'File' menu, select 'New', choose a storage location such as OneDrive, and click 'Create Notebook'.
Navigate to the 'Draw' tab, draw some sample ink on a new page, select the Lasso tool, and attempt to select the ink. If the lag disappears, your original notebook may be corrupted.

Perform a Windows Clean Boot
Start Windows with a minimal set of drivers and startup programs to identify if background software is interfering with OneNote performance.

Frequently Asked Questions
Can a large notebook cause the lasso selection tool to lag?
Yes, extremely large notebooks with excessive ink, high-resolution images, or heavily embedded files can consume high memory, causing OneNote to lag when rendering selection tools.
Why does OneNote lag only on my Surface Pro 8 and not on my previous Apple device?
This discrepancy could be due to differences in how the operating systems handle background services, hardware graphics acceleration settings, or specific Windows driver conflicts with the Surface pen.
How can I fix a corrupted OneNote notebook?
If your notebook is corrupted, create a brand-new notebook. Then, manually copy the sections or individual pages from the corrupted notebook into the new one, being careful not to copy damaged sections.
Will reinstalling Microsoft Office fix the lasso tool bug?
If the issue stems from corrupted application files rather than a corrupted notebook or background interference, reinstalling or running an 'Online Repair' for Microsoft Office can often resolve persistent bugs.
