Modifiers not rendering when Composite mode is Vector


I have a Curve modifier affecting a drawing, and this, along with other drawings, connected to a Composite.

When I change the Composite Mode to Vector, the drawing affected by the modifier appear in rendering as if it isn’t affected at all, even when it appears correctly on the OpenGL View.

If I change the Composite mode to any other option, Bitmap, Seamless Bitmap, or PassThrough, the rendering works again.

Is this problem normal? The documentation doesn’t say anything about limitations with Vector Mode (it mentions some limitations with Seamless Bitmap though)

I’m using Premium 15, latest build on Windows 10.
