Bug ID: 37109
           Summary: Tab control waits for two seconds and then hides its
                    children when its WS_TABSTOP/WS_EX_CONTROLPARENT
                    change
           Product: Wine
           Version: 1.7.22
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32

Source of program that demonstrates this bug. Only compiles with mingw due to
use of asprintf().

For simplicity's sake (and especially since I'm now going to need to make them
transparent...), my tab apges are all children of the tab control itself.
Because WS_TABSTOP and WS_EX_CONTROLPARENT are mutually exclusive, my tab
controls enable the latter before calls to IsDialogMessage() and enable
WS_TABSTOP after calls to IsDialogMessage(). The attached program is a basic
example with a tab that parents an edit control.

In wine, if you click the sole tab or press Tab while focused on the edit
control, you will notice that wine seems to stall for a few seconds, then the
tab receives focus and the edit disappears. If you press Tab again, the edit
reappears.

On both Windows XP 32-bit and Windows 7 64-bit, both with and without a
comctl32.dll v6 manifest, the focus switch happens instantly and the edit does
not disappear.

Using wine-1.7.22 from the official Wine PPA and a 64-bit WINEPREFIX
(apparently) on Ubuntu 14.04.

Thanks!

Do you see this lag with native comctl32 v5 running Wine? (after 'winetricks
cc580').

Sorry for the delayed response.

This bug still happens on wine-1.7.28 on Ubuntu GNOME 14.10 (stil from the
PPA). After winetricks cc580 it goes away.

I don't see a lag, but the content is replaced with white and pressing tab
again restores state.

wine 2.0rc5 and staging 2.0rc4. winetricks -q cc580 is a workaround.

Still valid.
