When sizing an MDI child code window the text gets drawn about two lines up and then redrawn at its proper place. It appears to be a problem with the VA toolbar at the top of the MDI Child window. It's like the window is redrawn as though the toolbar is not there, then redrawn with it there.
Using: Visual Studio 2008, with the Window layout in "Multple documents" mode. Visual Assist, version 10.4.1624.0 C++ Language No other Addins
To reproduce: 1) Run Visual Studio 2008 2) Click Tools->Options->Evironment->General->Multiple documents->Ok 3) Open a .cpp file 4) Grab the corner of the .cpp files MDI Window and size it 5) Notice the text get drawn twice in two different locations 6) Click VAssistX->Enable/Disable Visual Assist X 7) Size the .cpp window, notice the flashing is gone (along with the VA toolbar)
I tried to work around this problem by placing the VA toolbar at the bottom of the window instead of the top. VAssistX->Visual Assist Options->Advanced->Display->ViewContext and Definitionfields:->Bottom of soure windows.
With the toolbar at the bottom, notice that it get placed outside of the scrollbars. Try sizing the window using the gripper located at the instersection of the verticle and horizontal scrollbars. It does not size the window as intended!
When you have the context and definition fields at the bottom of the window just ignore the grab corner at the end of the scroll bar and grab the bottom right hand corner of the window. When I do this I can resize the windows normally.
It does not eliminate the flicker, but it does considerably reduce it.
