QT QML UI is not refreshing on embedded Linux Display Unit
-
Hai All,
I am running a Qt QML application with framebuffer gui backend on touch screen display. The application is divided into header , footer and body, where the body is changed as the navigation done to different pages. Header and footer remains the same for all the pages
Whenever I navigation to the Ui which has the scroll option and then navigate to other pages , I cloud see the previous page UI traces on the header and footer as shown in the below Image. Scrolling is implemented using Flickable QML component.
And When I display some popup message the previous UI traces disappears. It seems like popup message is refreshing the complete UI.
Before navigating
After navigating and scrolling
The blue lines can be observed on header and footer of the Ui.
How to prevent these traces appearing on the header and footers ?
Note : This issue is not appearing when I run on the Desktop.
