65K limit possibly leading to runtime crash using 1.3.0 and 2018.3.7f1

Hi Stephan

In a VR scene with Curved UI I have a TMProUGUI component in a ScrollRect that is set at runtime to a rather large piece of text which exceeds the 65K vertex count.

This appears to be causing a crash in the Unity Editor and on the Rift as well.

In the past I was able to set this to the text at design time and while the editor complained, it was able to build/run ok. However doing this at design time seems to be causing a crash.

Below is a quick summary, and attached is the full log in from the Development Build on Rift.

Hope you can suggest a way around this.


kind regards,

Nalin
