Bug 1077

Summary: full screen blank/reset at SQL_Quit() on Windows
Product: SDL Reporter: zerothat
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: Other   
OS: Windows (XP)   

Description zerothat 2010-11-17 14:16:43 UTC 
In SDL/src/video/win32/SDL_win32modes.c WIN_QuitModes(),

the ChangeDisplaySettingsEx(NULL, NULL, NULL, 0, NULL) call 

(which is defined to ChangeDisplaySettingsExA for me)

triggers a full screen black/reset.

Commenting out the ChangeDisplaySettingsEx call seems to eliminate the reset with no adverse consequences.

Looking at MSDN, I can't see a reason for this to fail.
Can you provide more details? Like, is it temporary or permanent? Does it happen everytime, or only under certain circumstances or even completely randomly? Does your application change any display's display mode or make a fullscreen window?

This is fixed in the latest snapshot, thanks!
