@font-face Thai fonts with Mozilla Firefox in normal mode can't rendered correctly, how to fix this?

It's a problem with text rendering, a tone mark stay above the place it should be.

In normal mode even with all my add-ons disabled, the problem still remains.

Note that, it rendered correctly only in safe mode.

Among all five major web browsers, the problem only happens with Firefox! This is a critical issue for Thai language when the web developers use @font-face in their website.

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

Try to toggle some Boolean gfx.font_rendering prefs on the about:config page to disable some features.
Filter: gfx

Some to try:

  • set gfx.direct2d.disabled to true to disable Direct2D
  • set gfx.font_rendering.directwrite.use_gdi_table_loading to false

This solution doesn't help at all. T-T

I think it's a bug.
