I have updated the machine (Windows update) and the Intel GPU driver stays the same. The issue still remains. However, I enabled the NV GPU and re-run the Gears Applet and voila .. ALT-TAB worked in fullscreen mode. Hence this is an issue w/ the Intel GPU. Further analysis hints that maybe: ChangeDisplaySettings(&dm, CDS_FULLSCREEN) is the issue w/ Intel GPU .. since this API is reported to cause problems: <http://stackoverflow.com/questions/3549148/fullscreen-management-with-winapi> <http://www.indiegamer.com/archives/t-796.html> We could find a remedy using GDI API (stackoverflow) or even go the DDraw route. More analysis might be required here. 3429 2 sgothel 2013-12-02 19:55:19 +0100 (In reply to comment #1) > Further analysis hints that maybe: > ChangeDisplaySettings(&dm, CDS_FULLSCREEN) > > is the issue w/ Intel GPU .. since this API is reported > to cause problems: > > <http://stackoverflow.com/questions/3549148/fullscreen-management-with- > winapi> > <http://www.indiegamer.com/archives/t-796.html> > > We could find a remedy using GDI API (stackoverflow) > or even go the DDraw route. > More analysis might be required here. Seems like we shall react on WM_ACTIVATE when in fullscreen mode: <http://www.gamedev.net/topic/588559-opengl--alt-tab/> i.e. revoke CDS_FULLSCREEN when becoming inactive and activate it when becoming active again. WM_ACTIVATE is sent in fullscreen mode when ALT-TAB switching. 3430 3 sgothel 2013-12-03 04:09:22 +0100 Remedy for 'some' display drivers, i.e. Intel HD: - Explicitly push fullscreen window to BOTTOM when inactive (ALT-TAB) 3434 4 sgothel 2013-12-04 03:32:11 +0100 (In reply to comment #0) > > But does not work on a laptop running Windows 7 > using an Intel HD 4000 w/ Intel GPU driver version > 8.15.10.2618 New Intel HD 4000 driver 10.18.10.3345 works w/o the remedy. However, applied remedy doesn't hurt and enables ALT-TAB for older drivers, incl. HD 3000.
