screen is mixed up when playing windowed

Post by madmaurice » Thu Jan 03, 2008 7:42 pm

when i choose windowed in options->video the game is windowed but my whole screen is mixed up in small parts of ca. 32x32. even windows is mixed up.

After quiting the game this problem stays.the way out is to choose again fullscreen and quit the game then.

when i tried to save a screenshot of this it was clear like it never happened Oo.

i'm looking for my camera tomorrow to take photos of my screen to upload them here.

That sounds really strange, a picture would definately help me to see what's going on.

Hello, I took the liberty to post a picture since I've got the same problem on Windows... (Works perfect on linux though)

[See edit below]

I'm using an ATI X800 XT.
Please let me know if you need any other information.

Edit: Removed the image, because the problem has been pinpointed.

Wow, that is really messed up. :twitch: I don't even know where to begin debugging that (and I can't, since I don't use Windows).


Oh and I deleted that user account for you as well.

And right you are. I'll probably make an attempt at debugging it when I get home today, I'll let you know what I find.

EDIT: No time to do so yet, will check when I got time.. :]

What version of allacrost are you using? Latest stable or latest svn?

Latest stable, since I can't get Allacrost to compile on Windows... But I haven't been really trying to fix that due to lack of time, soon perhaps!

Oh and I posted something earlier which I deleted, the bug only occurs while switching from full screen to windowed mode in game. I thought it happened because the previous setup surface isn't freed, but that seems to be working perfectly without freeing it in the current version of SDL.

If I could just get it compiled I could try some stuff.

Just noticed the same thing happened with Doom 3 when starting up, the problem is probably driver related. I already found it strange how the screen shot did look normal.

Yeah, this is most likely driver related and is likely triggered when you start graphic accelerated mode.

If you think you have the correct driver then try the following: Try to run "dxdiag", it's for directX but it should trigger the same issue. If it doesn't trigger, try to reduce your hardware acceleration (Configuration->Display properties->Tab Settings->Press Advanced->Troubleshoot) and then try again. Do it steps since the game might require the advanced (which are hardware accelerated) instructions.

If you have problems compiling on windows there is a huge tutorial on the forum which goes through it step by step.

Oh what I suspect that happend is that in the 3D acceleration mode there is a change in the pitch of your video resolution which messes up your screen.

Yeah, you're right. Disabling all advanced drawing acceleration got rid of the mess when switching. Though obviously it isn't really playable this way :-]
