Hey, I created two function that are used to toggle fullscreen mode.

Here it is:
core is the name of the class, it's a bunch of core functions.
_fullscreen is a bool to see if fullscreen is on or not. Used as a failsafe.



It works with turning on and off fullscreen, but there is one little issue that is bugging the hell out of me.

After returning to windowed mode, the sprites I am using look a little blurry. It's a bit hard to see, but normally, my game is in two different colors, black and white, but after returning, I noticed a bit of grey.

I'm not altering the resolution at all, dbScreenWidth() and dbScreenHeight() keep reporting the same numbers.

Got any Ideas?

The display mode size must match the resolution of the actual application canvas, otherwise you will get some distortion from filtering. Same thing if you run in fullscreen on a non-CRT at a resolution that's lower than that of your monitor.

Okay.

Well, do you have any ideas on how to "fix" it? I've tried dbSetWindowSize() and dbSetDisplayMode(). Both of them end up with the same unwanted result when I restore the window.

I guess I solved my own problem when I tinkered with the code a bit.



For some reason, if change the second parameter of "dbSetWindowLayout()" to '0', I don't have this issue.

Anyways, I think though I may have found a possible bug:

First off, I was using the resolution of 1024x576 (16:9 ratio), well, when I would toggle fullscreen on then off, I'd get the blurry canvas (if dbSetWindowLayout() 2nd's parameter was '1') when I was back in windowed mode.

Well, I used the dbScreenWidth() and dbScreenHeight() functions to tell me what the resolution was 1024x576. Both in fullscreen and windowed mode.

Well, this looks a little suspicious since the windowed mode is now blurry. I did a screen cap of before I turned on fullscreen, the canvas was 1024x576, then I took another after I toggled fullscreen on then off, the screen cap showed I had a resolution of 1022x574. Oddly enough, dbScreenWidth() and dbScreenHeight() reported 1024x576.

Something seems off here.

Well, in the code if I tried to use dbSetDisplayMode() or dbSetWindowSize() (after toggling on then off fullscreen mode), and punched in '1024' and '576', I would still have the blurry canvas (and the actual resolution would be 1022x574).

So I think that if the second parameter in dbSetWindowLayout() gets set to '1' can mess up some things.

So should I report this bug?
