#1834 closed defect (fixed)

GUI: Starting games in fullscreen doesn't work

Reported by: SF/trinity78 Owned by: cyxx
Priority: blocker Component: Ports
Keywords: Cc:


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
#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
#4 0x00406b97 in runGame(GameDetector&, OSystem*)
system=0x1078428) at base/main.cpp:263
#5 0x0040708c in main (argc=1, argv=0x3f2570) at

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

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 :-)
