Text mesh pro corruption issue

Strange one, we have been using textmesh pro fine with no issues for ages and today on user has reported text corruption after playing for a few minutes everytime she plays, I think there are a few other reports we have had, just no screenshots.

this was on a Samsung Galaxy J1 Mini, anyone else had similar font corruption issues ?

Yep, its caused by using the same font in 2d UI and then using the same font in a 3d scene. You need to duplicate your font styles. We duplicated the set and added _3d on the end and just used that set for 3d scenes.
