FNC components adhere to standard FMX styling via Tstylebook, this is quite cool and an improvement. However, the renderings in detail are suboptimal in some places:
TTMSFNCDirectoryEdit is using a TTMSFNCEdit + TTMSFNCToolBarButton. From your screenshot it's not immediately clear what is rendered differently. Can you please clarify what should we look for exactly?
In TTMSFNCDirectoryEdit the TTMSFNCEdit is a child control. It's being cut off because the ClipChildren property is set to True by default. We'll look to make False the default value but in the meantime you can simply set it to False manually.
