Description razinov.a.u 2013-02-10 19:22:31 UTC

See screenshot. It is well descriptive.

Reproducible: Always

Steps to Reproduce:
1. Receive file via skype (maybe, HTTP also suits). It must lasts long time.
2. Open file in gwenview.
3. You should see partly downloaded image, the part of image, that is not already dowloaded is black. Let name this area BLACK. And other area - DOWNLOADED.
4. Zoom in. You must be able to move the image with the hand tool.
5. Move image down.

So both BLACK and DOWNLOADED areas go down, part of BLACK area will intersect previous DOWNLOADED area (logically):
before move: BBBBBDDDDD (BLACK and DOWNLOADED visible areas; B is actually on the top of the screen, and D is on the bottom).
after move: BBBBBBBBDD (areas go down).
So black area moves to downloaded. Intersection: BBBBBxxxDD. The problem is within the intersection (xxx).
Actual Results:  
6. BLACK area remains the contents of DOWNLOADED image, when it became within BLACK area. In other words, it is not cleared as expected.

Expected Results:  
6. BLACK area will be still black.

You can use a static file that is downloaded partly. So neither skype nor HTTP download will be needed.

Hope you understand this description. It is a minor appearance bug. But I think gwenview will be more perfect after someone fixes this.

Can you reproduce this with a more recent KF5 version of Gwenview?
