I found Zawgyi didn’t work well in Chrome, Window 8. It seems font rendering conflicts. It can solve with Chrome custom style sheets. The following steps will solve this.

For those who didn’t have Zawgyi Keyboard, https://www.dropbox.com/s/dz50rsc5hyjt3ou/zawgyi-keyboard-layout-l.zip

1. First of all, we have to change file hidden in the Chrome app directory structure

C:user_dirAppDataLocalGoogleChromeUser DataDefaultUser StyleSheetsCustom.css

In my file structure,

2. Open “Custome.css” and Past the following code to that file.

* , html, body, div,p {font-family:Zawgyi-One !important;}

3. Then save that file and it is supposed to be worked.
