# Switching "Types of render" between Default and Canvas changes nothing

**What you are seeing**

Switching "Types of render" between Default and Canvas changes nothing.

---

## Why it happens

The option has no effect. It is kept only so macros created by the original Connect app round-trip without losing data.

---

## What to do

Leave it on Default. If rendering looks wrong, try Render Text Layer instead.
