- Scenario
- Searching for specific text and scrolling through a PDF document using the Find tool.
- Observed behavior
- Scrolling becomes noticeably slow, lagging, or jittery while the Find dialog is open on the screen.
Ensure you are using the most recent version of Adobe Acrobat, and temporarily close other background applications to free up system memory before troubleshooting.
Adjust Page Display and Rendering Preferences
Modifying how Acrobat renders pages and handles smooth scrolling can often resolve jittery performance while the Find tool is active.
Acrobat's advanced rendering features can sometimes conflict with the active Find dialog, consuming excess resources and causing visual lag. Disabling these visual enhancements can restore smooth scrolling.
Launch Adobe Acrobat and go to Edit > Preferences (or Acrobat > Settings if you are on a Mac).
Select 'Page Display' from the Categories menu on the left side of the Preferences window.
Under the Rendering section, locate and uncheck the 'Use smooth scrolling' option.
Toggle the 2D graphics acceleration setting or change the 'Smooth Text' dropdown to see if software or hardware rendering improves performance.
Click 'OK' to save your changes, then restart Adobe Acrobat and test the scrolling performance with the Find tool open.
Increase System Memory Priority for Acrobat
Allocating higher system priority to Acrobat can prevent lagging when searching through resource-heavy or heavily annotated PDFs.

Frequently Asked Questions
Why does my PDF reader lag when the Find tool is open?
The application can lag because the Find tool continuously scans document text, layers, and annotations in the background as you scroll, which consumes a significant amount of memory and rendering power.
Does disabling smooth scrolling improve PDF performance?
Yes, turning off smooth scrolling in your PDF reader's Page Display preferences reduces the rendering workload, which can eliminate visual stuttering and jittery scrolling.
How do I check if annotations are causing the slow scrolling?
Try opening a text-only PDF that contains no highlights or comments. If the scrolling is perfectly smooth with the Find tool open, the issue is likely related to how the software renders complex annotations during an active search.
