Could you type about:support in the location bar and paste the section "graphics".

Maybe a dupe of bug 1345379.

It's probably a dupe of bug 1345222 which is going to be fixed in 53+.

Could you download Beta in a few days and test again to check if it's fixed.

Can you go to about:config, and set the preference "gfx.content.azure.backends" to "cairo" and see if that fixes it for you?

Yes.. That fixes it. Thank you very much :)

JFYI.. The preference "gfx.content.azure.backends" was set to "direct2d1.1,skia,cairo".

Thanks again.

I don't think there is much we can do here. Since this is on Windows XP, the best bet is to revert to cairo. XP is end of lifed.
