Hi elysia,

Thank you for reaching out, and sorry for the trouble caused.

We tried to open the PDF you shared above, and it opened fine on our end. As it happens, with a particular PDF, there could be a few reasons causing this behaviour.

• Large embedded images, scanned content, or complex vector elements can slow rendering.

• Fonts, layers, or hidden objects may cause repeated reprocessing.

• GPU-related issues can delay page display.

• Acrobat may attempt to process scanned pages in the background.

Please try the following troubleshooting steps and 

1, Test with Page Display Settings: Go to Edit > Preferences > Page Display. Try the following:

• Enable Use 2D graphics acceleration (or disable it if already enabled)

• Set Rendering to Smooth text OFF (for testing)

• Restart Acrobat and reopen the file.

2. Disable Protected Mode (for testing): Go to Edit > Preferences > Security (Enhanced). Uncheck the following:

• Enable Protected Mode at startup

• Restart Acrobat

3. Flatten or Re-save the PDF. Use the following steps:

• File > Save As > Reduced Size PDF

• Or print to PDF: File > Print > Adobe PDF

4. Reset Preferences

• Close Acrobat

• Rename the Preferences folder:

              C:\Users\<username>\AppData\Roaming\Adobe\Acrobat\<version> 

​​​​​​​​​​​​​​5.Try reinstalling the application using the steps suggested below:

•  Remove the application and run the cleaner tool (https://adobe.ly/4nfzl1s).

• Reboot the machine.

• Install Adobe Acrobat from the following page: https://adobe.ly/4nfzmCy.
