Google chrome rendering pdf fonts incorrectly

All we need is an easy explanation of the problem, so here it is.

Some PDF files I open in Google chrome are completely unreadable, here’s an example picture:

here's an example picture.

This is the original PDF.
They are shown fine on normal pdf viewers like Acrobat or Sumatra.

I have chrome version version 59 and haven’t really found anything on the net.

What should I try?
Thanks for the help!

I also tried enabling or disabling hardware acceleration in chrome, but it didn’t help. The problem is that there are no pdf viewer settings in chrome at all, so I have no idea what to try.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

I had the same issue, just uninstalled a font called “Alien League Tech”, rebooted, and all came back to normal. Explanation is here:

Other way of solving: Enabling the “Disable DirectWrite” experiment on the Chrome Flags page ( chrome://flags/#disable-direct-write ).

Method 2

Using Powershell with administrative privilegies, go to Fonts folder

cd c:/Windows/Fonts

than remove alien5.ttf

rm alien5.ttf

Windows 10 Fonts viewer via Windows Explorer doesn’t show everything. There’s a lot of fonts hidden underneath.

Method 3

This error occurs when you install a custom font and the file name falls in the line before Arial.ttf. 🙂
Copy the Arial.ttf file into a temporary directory, rename 001-arial.ttf and then install it to the Windows font.
The point is that the file extensions should be the first-ever TTF WINDOWS \ Fonts folder.

Method 4

Same problem with strange "alien league" font being displayed in random pdf files.

I had to rename the file "alien5.ttf" (to "alien5.ttf.problem" ) using admin privileges in the \windows\font directory and then reboot. I could not figure out how to remove the font using normal windows tools. Windows explorer would not show the "alien" font when I was viewing the \windows\font directory.

I never want to see that font again. ever.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
