--- Comment #14 from Igor Tarasov tarasov.igor@gmail.com 2008-12-29 11:57:30 --- Yes, the problem still exist in 1.1.11.
License agreement does not allow us to do so, but I'll try to contact the developers and see how they can help. Meanwhile, I have exchanged a couple of emails with one wine developer, Mikołaj Zalewski. Here is what he said about this bug:
This looks like a rebar layout problem. I have already fixed some layout problems and know this code well so I could try to check what is wrong. What you could check is if minimizing/maximizing the window would change anything - there are some redraw problems that are not fixed (it looked to me that they even are in user32, not comctl32). If it changes, attach the screenshot of the window after this operation.
So, I've answered:
Well, it's not that noticeable when you minimize/maximize window, but it's much more noticable when you resize the left bar.
http://www.polosatus.ru/wine/wtlibcalm.png displays program interface when it is loaded. You may see empty space at the left bar - there is missing toolbar. Another problem is partly misplaced left toolbar (it is a bit left and down from its original position). You may compare it with reference rendering from bug description (it uses different program version, but bug is the same):

Now, when you change bar width, toolbar flickers a bit. The first thing that flickers there (not always noticeable) is the top input field and search button. Hardly, but I've caught it for a screenshot, see http://www.polosatus.ru/wine/wtlibflicker1.png (i've made right bar a bit wider and it redraws).
Then, it disappears, and you can see the missing toolbar ( http://www.polosatus.ru/wine/wtlibflicker2.png ) and then it disappears and interface returns to http://www.polosatus.ru/wine/wtlibcalm.png
But Mikołaj never responded.
