GUI Guider 1.4.0 -> LVGL v8.2.0 -> LPC54S018
Within GUI Guider creating a Spinbox Widget that has 0 digits after the decimal place seems to cause a rendering issue that affects most of the items within that screen. Objects disappear and then will usually reappear if selected from the screen menu on the left side. But the Spinbox Widget itself also renders incorrectly (see screenshot below).
I think this only impacts working within GUI Guider. Once the code is actually running the objects display correctly. At least with the Simulator (C) I haven't verified on hardware yet.
