Sailfish browser display redraw delay

I have noticed, that there is this strange delay until screen is redrawn when you pan your screen. This happens at least with Sailfish browser and Maep GPS app. Sailfish maps application does not show suffer from this delay. This thing has been there since the beginning.

How to reproduce:

  1. Open Sailfish browser (portrait orientation) and go to a web page (for example www.uutimet.net a light text page without graphics).

  2. Zoom the web page to a 2-3 times the size of screen width. So that you can pan the screen later on.

  3. Put your finger on the glass near the left edge of the screen.

  4. Swipe your finger to the right edge of the screen and hold your finger on the glass.

  5. Look at the left edge of your web page. The left edge is white without page contents. Web page content which was hidden outside the display screen before you pulled it to visible screen area is not showing on the screen.

  6. hold your finger on the glass ... left part of the display stays empty ....

  7. lift your finger off the glass. Notice how the missing web page content is immediately drawn on the display after you lifted your finger.

Could this delay be removed ? This is disturbing the use of Sailfish web browser and panning the map with Maep application.

How to reproduce:

Update: Simply scrolling up and down in portrait mode through pages with many prelpaded links, graphics, or GIFs, causes a delay in rendering and white out of entire sections. The problem below still exists but instead of white now sometimesboccurs as slighly blurry partially rendered text that wont disappear until remove finger from screen.
