I know a while back some trees got fixed so that you can right click for tint and no tint, however I just found that the canopy and plane touched ones are also affected by the weird bug.

The top two trees are Small Canopy Trees and the bottom two are Small Planetouched Trees. I can only guess the other sizes do it too.
