Screen Widgets flickering through to lv_layer_top()

Here is the scenario using LVGL Version 8.3.6:

I have a base screen with buttons and panels. Then upon user clicking I place another panel on the lv_layer_top() which XY pos covers over some of the screens widgets. In this lv_layer_top() panel there is a dropdown. As the dropdown is scrolled, the refreshing causes widgets underneath lv_layer_top() to momentarily render through the lv_layer_top() causing flickering. If I hide the widgets underneath while the lv_layer_top() is active, no flickering occurs.

Is this an issue?

Thanks.

Hi,

Having a dropdown on the top layer could be a special case. Could you send a small code snippet to reproduce the issue?
