[RC1] Alt-tabbing does not work on windows 7 64

[Jorsku]

Cant get back to game when alt-tabbing out of full screen game. worked fine on 43
seems only hang when on game not on starting screen (new game, load etc..)

Similar for me with an ATI card on win 7 32.

Except I could get back in, but fullscreen had been displaced and was sort of windowed mode, but without the ability to move or resize it. Changing resolution sort of fixed it the first time. Completely fixed it the second time.

Oddly it worked fine after I left Point Zero.

I have this too.

XP - same problem.

Some of the same bug: When I suspend with the game active & fullscreen on Win7, I get the game backgrounded as with b43. When I click the icon to foreground the game, I get the game without window widgets (as if fullscreened) but positioned about halfway down and across my screen. If I Save & Exit from this state, loading the game menu causes a graphics changes and puts the game back into full screen mode again.

Same issue here, Vista 64bit. On tabbing back in ToME ends up at the wrong position in a weird windows mode. Changing resolution fixes it but leaves the hardware mouse pointer at a slightly wrong position (the mid of the cursor is where it points to, not the tip as it should be). Can't check if Save and Exit and going back in would fix it because of a BSOD.
Worked fine in beta 43

Pretty much the same. Windows XP. I can't even change resolution properly without game hanging, have to do this manually via config file. High resolutions like 1280x1024 FS (my monitor's standart) or 1200x1024 Windowed hang the game at start, or after alt-tab. Smaller ones like 1152x864 work and allow alt-tab. Everything was fine in b43.

I can confirm this behavior on both ATI and Nvidia machines. As Jorsku mentioned, this only happens while in the tome module. While in the boot module, the screen can be alt-tabbed without issue.

The main part of the issue is that alt-tabbing is leaving the game in borderless windowed mode. When focus is returned to tome, the game stays in windowed mode unless forced to fullscreen via a video mode change. This could be an issue from upgrading SDL (if SDL now allows for more flexibility wrt to switching window focus).

A minor part of this issue is that tome's window position is being forced down and to the right. This is related to the window.pos setting. When you start the game in windowed mode, it reads this value and places the window in an initial starting position specified by window.pos. I think the intention is for window.pos to be saved when the window is moved so that when you load up t-engine again, you don't have to reposition the window. However, window.pos is currently ignored, causing the window to spawn at a fixed offset from the upper left of the screen (560, 240 for me, may be based on percentage of the current resolution). This makes alt-tabbing in fullscreen mode a double-whammy. Not only is it forced into windowed mode, but the window is offset by a rather large amount from the top-left of the screen.

In any case, thanks everyone for reporting the issue. My recommendation would be to use windowed mode until this issue gets fixed in the next release candidate. Other people seem to be having issues with the older SDL revision, but an alternative executable with older SDL dlls might be posted as a temporary solution until RC2 gets out.

RC1 executable with old SDL. Extract over your existing RC1 installation. This temporarily solves the fullscreen alt-tab issue. You should be able to load any existing saves and the game will still validate.
