[2.0.3]-Full Screen Desktop Fails On Linux?

Hi,

We are trying to make a cross-platform game using SDL2 v2.0.3.
We have everything working 100% on Microsoft Windows platform.

We have a problem with full screen desktop failing to work on Linux(Linux Mint 17.1 KDE 64Bit)?
Here is our code:
Code:
if (visuals->FullScreenMode == false)  SDL_SetWindowFullscreen(visuals->Window, 0);
else if (visuals->FullScreenMode == true)  SDL_SetWindowFullscreen(visuals->Window, SDL_WINDOW_FULLSCREEN_DESKTOP);

Is there a problem with our source code which would make full screen desktop fail to work properly on Linux?
Again, it works 100% perfectly on Microsoft Windows platform.
Thanks in advance!

Hi,

We got full screen desktop working now on Linux.
You have to unload all textures before changing the game's window
and then reload all textures after...

Thanks!

Hi,

We spoke too soon...
Full screen desktop is again not working on Linux(Linux Mint 17.1 KDE 64Bit)?
Anyone know why?
(it's SDL2 ver. 2.0.2 from Synaptic Package Manager)

Here is a screenshot:

Are you also setting the window size to match the desktop resolution?

Hi,

How would I do that?
I mean which SDL2 functions would I use?

Thanks...

Hi,

Ok, so I think we've fixed full screen desktop mode on Linux.
You have to both reload textures and reinitialize the renderer...
