Before trying to solve the problem,... we need select windows? What's the purpose of select windows? I don't use it, but probably I am missing something :-?
Never used it either but I can imagine it may be a useful feature for someone. The idea is that you can select some windows (or miniwindows) and then apply an operation to all of them at once. For example you can move them together. There are at least three ways to select windows: using the Select item in the window menu, Shift+click on the title bar or starting a drag on the root window and enclosing the windows with the rectangle. Selected windows have a white border around them.
Not sure if this helps or answers your question though. As for solving it, I'm not sure if there's a way without a grab or otherwise hiding changing parts of the display, because the drawn rectangle has to be reverted and if screen content changes it's not possible. (By the way, there's a simple way to see this if you have dock apps that have some moving content e.g. wmnd or a cpu load monitor or you can start 'xclock -update 1'. These will all stop when the select rectangle is being drawn.) Maybe it could be circumvented by not drawing the rectangle but using a transparent window instead (with only a border) but it may not be easy to implement or compatible with all versions of X and the same grab also happens for example when resizing a window with the technical drawing like size display so it would not fix all cases either.
So I think you could close the bug as "wontfix" with an explanation and advise disabling the Select Windows in Prefs if someone is annoyed by it.
