Bug#556031: libgtk2.0-0: treeview+scrolledwindow redraw issues when inserting and removing rows

[mikel garai]

Package: libgtk2.0-0
Version: 2.18.3-1
Severity: normal

Ok, I know this will sound a little confusing because it happens in  very specific situation, but I will try to make it clear. And sorry in advance for my English

The situation is the following: 

I have a treeview inside a scrolledwindow.

The treeview have a lot of rows so the vertical scrollbar is shown and enabled.

I scroll down to any point, making sure that there are rows that are not shown in the beginning.

If a row is removed and then another row is added before repainting on the area of the treeview that is not visible over the visible area, the treeview is not repainted properly. The artifact is that the last column is correctly repainted and the rest of the columns are not, they appear one row displaced up until another repaint is triggered (for example by the mouse moving over them).

I add a simple python script with a basic example of this behaviour (extracted from the pygtk tutorial), it just have a timeout of 2seconds that removes the 3rd line of the treeview and add just there a line, to see the artifact just scroll down so the 3rd line is totally out of the visible area and select any line, you'll see that even the cursor and selection are not properly redrawn. 

I add this script for simplicity, but I am reporting this to general gtk2 because it happened to me in gtkmm too, so I'm guessing that is a gtk issue.

Thank you,

Mikel
