Description
When using the scale widget and sections on it, I run into issues when using page transition animations (fade in). During the animation, the section arc is drawn always fully opaque instead of fading in.
All other used controls on the screen (buttons, labels, etc.) are fading in correctly.
What MCU/Processor/Board and compiler are you using?
STM32H7 / GCC
What LVGL version are you using?
9.2.2
What do you want to achieve?
Drawing scale sections with custom color and thickness.
What have you tried so far?
Setting Background color, opacity and arc opacity.
Code to reproduce
auto &style = m_sectionStyles.emplace_back();
lv_style_init(&style);
//lv_style_set_bg_color(&style, lv_color_black()); // no change
//lv_style_set_bg_opa(&style, LV_OPA_0); // no change
//lv_style_set_arc_opa(&style, LV_OPA_COVER); // background shines through if set at low value
lv_style_set_arc_color(&style, to_color_t(NamedColors::yellow()));
lv_style_set_arc_width(&style, 11);
lv_scale_section_set_style(pSection, LV_PART_MAIN, &style);
