Hello

Suddenly, my pdf thumbnails appear inside of a kinda white square, like this: https://i.ibb.co/0B5ggMW/white-borders.jpg

I have no idea why this started happening, but installing an older Adobe Reader version has not helped and I cannot undo the most recent Windows update anymore.

I've tried these, but neither helped:

- Clear Thumbnail Cache

- Delete IconCache.db

- Use this fix

- In Adobe Reader, turn off and on miniature preview

Between these steps, I of couse always restarted the computer

I want it to look like this: https://i.ibb.co/Xs2bCSZ/correct.png

(for some reason, I have this problem only on my laptop, but not on my desktop pc, even if both are the same Win 10 version, same updates, same Reader version, etc)

Does anyone have an idea how to get rid of that?

Thanks

Hello. Just wondering if you ever found a resolution to this problem? I am currently trying to figure out how to get rid of that same white border on the pdf thumbnail. We made a jump from windows 7 to windows 11. Windows 7, our thumbnail pdf file previews didn't have the white border, but windows 11 thumbnails do. Thanks for your time! Adam

I have the same problem. Apparently the ACROBAT 64-bit preview handler does not take transparency or alpha blending into account. The old Acrobat 32 bit preview handler did it right and took transparency into account and it looked very nice. Since 64 bit so for about ten years the limitation exists. Now I wonder why Adobe doesn't fix the problem. It's not essential, but it used to look much nicer.

Adobe does a lot of advertising with new technologies etc., but I can't take it seriously if something so fundamental is not corrected.

Hi @Michael_X15,

Hope you are doing well. Thanks for writing in!

I was going through the thread, and from the description, this is an Explorer issue, not related to Acrobat.

One suggestion I would like to add is to go to the Start Menu, type "File Explorer Options, "go to the View Tab, uncheck the option "Always show icons, never thumbnails", apply, and then OK.

Once done, go to Start Menu-> type "Disk Cleanup"-> scroll down the list to check "Temporary Files" and "Thumbnails"-> OK-> click "Delete Files" on the next window-> allow for it to complete.

Restart the computer and then try again.

Hope this helps.

I have the same problem. I'm going to be crazy, but none of the solutions works for me. I just updated from Acrobat DC 2019 to 2023 and the problem started to appear.
