[EFL]Drawing artifacts while resizing the view

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Kalyan]

Launch MiniBrowser. Try resizing the view. The updates are not smooth (just horrible currently).

[Kalyan]

This is observed with AC enabled and using webkit2.

After the above bug fix, situation is far better. We don’t see any empty tiles but still there seems to be flicker issues

Investigating the flicker issues.

Will wait till 103428 is fixed to see if we still see the flicker while resizing the view

Removing dependency on 103428

Create a GL surface here so that Evas has no chance of painting to an empty GL surface.
