Bowser Widget Flicker [message #1499922]

I'm embedding an HTML5/javascript plotting package into my rap application using the browser.setText() method, which works well. The underlying data changes however based on a user interaction (for example a slider), which calls browser.setText() again with a new plot/data. When this occurs the browser widget briefly repaints with the background color, and then draws the new plot, causing a flicker.

Are there any suggestions of a way to get the browser widget to not flicker (due to redrawing with the background color) on an updated call to setText()?

Thanks!

Hi,
Browser#setText generates and sets new HTML page in the browser widget.
It's normal to have flickering when page is (un)loaded. You could try to
update your data by executing JavaScript with Browser#evaluate.
HTH,
Ivan
