Hi,

if my app is running in fullscreen mode on a Windows 8 tablet, and the user rotates the tablet by 90 degrees, troubles start...

The good news is that a resize event arrives. If the normal fullscreen resolution is 1366x768, then the resize event usually reports 768x1366 (which is perfect), but not always, sometimes I get something broken like 768x1351 or so.

The bad news is that the function below doesn't get the new display modes after a 90 degree rotation, since it uses '!display->num_display_modes'.

SDL_GetNumDisplayModesForDisplay(SDL_VideoDisplay * display)
{
    if (!display->num_display_modes && _this->GetDisplayModes) {
        _this->GetDisplayModes(_this, display);
        SDL_qsort(display->display_modes, display->num_display_modes,
                  sizeof(SDL_DisplayMode), cmpmodes);
    }
    return display->num_display_modes;

I fear the SDL code can currently not handle resolutions that change at app runtime..

Best regards,
Elmar

My suspicion is we have fixed this since 2013; going to close for now.

Actually, wait, we can handle orientation changes, but I'm pretty sure we can't handle dynamic display resolution changes. Putting this in 2.0.18 for consideration (but possibly it gets kicked to a later milestone).

I added the dynamic orientation change event on Windows and set up the infrastructure for a resolution change event, if we want to add one.
