How to Fix Highlighted Text Turning White or Invisible in Acrobat
Question details
Users experience highlighted text becoming white, transparent, or completely invisible when attempting to view or edit a PDF document.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Highlighting text or entering Edit PDF mode in a document.
- Observed behavior
- The text disappears or turns white underneath the highlight, making it impossible to read instead of displaying the highlight color correctly over the text.
Ensure you have saved a backup copy of your PDF document and check whether this invisibility issue occurs across all your PDF files or is isolated to one specific document.
Disable Hardware Graphics Acceleration in Acrobat
Turning off hardware-accelerated rendering often resolves graphical glitches and display conflicts that cause text to vanish.
Adobe Acrobat uses hardware graphics acceleration to speed up rendering, but conflicts with your system's graphics card can cause text layers to render incorrectly, especially when highlights are applied or when switching to Edit mode.
Launch Adobe Acrobat, click on 'Edit' in the top menu bar, and select 'Preferences' (or press Ctrl+K).
In the left-hand categories pane, click on 'Page Display'.
Under the 'Rendering' section, uncheck the box labeled 'Use 2D graphics acceleration'.
Click 'OK' to save your changes, then completely close and reopen Adobe Acrobat to see if the highlighted text displays normally.
Update Graphics Drivers and Adobe Acrobat
Outdated display drivers or software bugs can cause rendering issues with highlights.
Recreate the Text or Re-export the Document
If the issue is isolated to a single file, the document's text encoding or layers might be corrupted.
Highlight and Edit PDFs Flawlessly with WPS Office
Avoid rendering glitches, invisible text, and hardware acceleration errors by managing your PDFs in WPS Office. WPS provides a highly stable, lightweight environment for reading, highlighting, and editing PDF documents without compromising file integrity.
- 1. Open your PDF in WPS: Launch WPS Office and drag and drop your PDF document into the workspace.
- 2. Select the Highlight Tool: Navigate to the 'Comment' tab at the top and click on the 'Highlight' icon.
- 3. Highlight the Text: Click and drag your cursor over the text you wish to emphasize. The color will apply smoothly behind the text without hiding it.
Frequently Asked Questions
Why does my text disappear only when I click on it in PDF?
This usually happens in 'Edit PDF' mode due to a conflict between the PDF editor's rendering engine and your system's graphics card. The software attempts to isolate the text block for editing, and a rendering failure causes the text layer to drop out or become transparent.
How can I change the highlight color to see if it fixes the invisibility issue?
Right-click the highlighted area, select 'Properties', and choose a different color from the 'Appearance' tab. Sometimes, a file-specific transparency glitch affects only certain colors. Lowering the opacity slider in this menu can also make the underlying text visible again.
Does 'Edit PDF' mode affect how document highlights appear?
Yes. In 'Edit PDF' mode, Acrobat processes text blocks as editable elements rather than static images. If there is a graphics glitch or a corrupted font subset, highlights may accidentally mask the text. Switching back to the standard viewing mode will often restore the document's normal appearance.
