Slider Knob not rendering correctly

We are running some tests of a mixer screen and are just using a simple implementation of a slider knob, background + border.

The knob border is rendered in the right location but as the image shows, the backgrounds are all over the place. A previous test using images with knobs was ok.


  • SLS v1.2.3
  • macOs Ventura 13.2.1

Could you send a very simple code snippet to reproduce the issue?
Just one slider would be perfect.

After updating the LVGL and VGLite libraries, this bug has been resolved.

The updated versions are as follows
GPU Driver: VGLite 3.0.15_rev7
Graphics Library: LVGL v8.3.2
