Trouble using vector graphic

How-to
1

Description

I’m having a problem using vector graphic on a canvas. Even the example doesn’t display the blue triangle in the lv_example_canvas_8 example, only the grey background is displayed.
The other canvas examples work…

What MCU/Processor/Board and compiler are you using?

I’m using the Visual Studio Simulator

What LVGL version are you using?

The latest 9.2

What have you tried so far?

I have tried to run the different canvas examples.
I have enabled the followings in the lv_conf.h:
#define LV_USE_FLOAT 1
#define LV_USE_MATRIX 1
#define LV_USE_VECTOR_GRAPHIC 1

Is there any setting which must be enabled to use vector graphic?

I’m not sure if there is a connection between this issue and another one I have found. When I start any application using the VS environment, I get the following error message: lv_display_refr_timer: No draw buffer lv_refr.c:374.

I’ve tried running the lv_demo_vector_graphic_buffered demo and it only displays an empty screen too.

Also, if I turn the monitoring feature off, nothing is displayed if there is no animation running.
