This bug applies to Su Doku Active by Greenstreet Games. Unfortunately I don't think there is a freely-downloadable version of this game.

When running in virtual desktop mode, the window title text flickers as the mouse is moved. There is no flickering in Windows XP.

The game requires MFC42.DLL, so it could be some call to that which is calling SetWindowTextA repeatedly as the mouse is moved. It may be that Windows checks the title text being set, and optimises out the rendering if the text is the same as the existing title.

Attached is an extract from a WINEDEBUG=+relay log which shows several calls to SetWindowTextA.

Is this still an issue with Wine-1.3.37 (or newer)?

Comment 2 Bruno Jesus 2013-01-21 13:40:03 UTC

Mark, is this still an issue? Or is this still relevant? Otherwise it will be closed as abandoned.

Comment 3 Mark K 2013-01-31 10:00:21 UTC

I tested Su Doku Active with Wine 1.5.22 and the problem is gone, at least with the default Wine settings.

Out of interest I did a regression test. The commit which changed things was:

    It can be disabled by setting "ClientSideGraphics"="n".

If I create the HKEY_CURRENT_USER\Software\Wine\X11 Driver\ClientSideGraphics registry key and set it to N, the flickering comes back. It might be that with the now-default ClientSideGraphics=Y, rendering is much faster so flickering is not noticeable, but this issue is still technically present.

Fixed.

Comment 5 Alexandre Julliard 2015-02-20 08:26:29 UTC

Closing bugs fixed in 1.7.37.
