|
|
* What happens is that we call AwtWindow::UpdateInsets when

|
* processing WM_NCCALCSIZE delivered on programmatic deiconification.
|
|
* At this point IsIconic returns false (so UpdateInsets proceeds),
|
|
* but the rect sizes still seems to be those weird of the iconic
|
|
* state. Based on them we compute insets with top = left = 0 (and
|
|
* bottom and right that are completely bogus) and pass them to
|
|
* PaintUpdateRgn which results in incorrect clip origin. Immediately
|
|
* after that we do UpdateInsets again during WM_SIZE processing and
|
|
* get real values.
