#1834 closed defect (fixed)

GUI: Starting games in fullscreen doesn't work

ScummVM Daily Build 0.7.0 CVS Windows 2000 Service Pack 4

If you start ScummVM in window mode and then switch to fullscreen using the alt+enter button, ScummVM exits/crashes without an error message when pressing the "start"-button. For some strange if you start a game in window mode and after the game has started switch to fullscreen using alt+enter, everything works fine.

Sorry typos: alt + enter button = alt + enter keys For some strange "reason"

I'm tired. *sigh*

Found the error message: Assertion failed: _transactionMode == kTransactionNone, file backends/sdl/graphics.cpp, line 1153

It was fixed couple days ago. Use latest build.

Hmm ok. In this case the Windows Daily Snapshot (November 28, 2004, 4:40 pm) seems to be quite old, because I downloaded it one hour ago.

Couple of days = couple of hours maybe?

To reproduce the bug: 1. Run ScummVM without parameters 2. Switch to full screen mode 3. Run any game

I add a quick look at it. For the reference, here's the backtrace : #0 OSystem_SDL::undrawMouse() (this=<incomplete type>) at backends/sdl/graphics.cpp:1153 #1 0x00402f7b in OSystem_SDL::setFullscreenMode(bool) ( this=<incomplete type>, enable=false) at backends/sdl/graphics.cpp:564 #2 0x00402072 in OSystem_SDL::endGFXTransaction() (this=<incomplete type>) at backends/sdl/graphics.cpp:78 #3 0x004c52e6 in Queen::QueenEngine::init(GameDetector&) ( this=<incomplete type>, detector=@0x22ff18) at queen/queen.cpp:333 #4 0x00406b97 in runGame(GameDetector&, OSystem*) (detector=@0x22ff18, system=0x1078428) at base/main.cpp:263 #5 0x0040708c in main (argc=1, argv=0x3f2570) at base/main.cpp:389

Basically, a call to undrawMouse() is made from setFullscreen() with _transactionMode == kTransactionCommit

As I am not that familiar with the SDL backend nor the transaction stuff (_sev told me it was semi-implemented), I can only give 2 suggestions : - change the assert in undrawMouse to accept the kTransactionCommit (quite hackish) - remove the undrawMouse() call in setFullscreen(); afterall, is it really necessary ? setFullscreen() calls internUpdateScreen() which refresh the whole screen and call drawMouse()....

Actually, the undrawMouse() is needed, because otherwise the mouse may leave traces in some systems (like in mine, because it switches between 555 and 565 mode; so when we switch the mode, the data gets converted, except the data behind the mouse).

So I commited the first suggested solution, I don't think that it is *that* hackish, actually :-)
