Description Michel Rouzic 2018-11-28 22:37:33 UTC 
After I initialise my window I call SDL_SetWindowPosition() to move the window to an arbitrary position. The problem is that if the requested position isn't the actual position, for instance I set it to (0, 26) or even (0, 0) but the actual position due to the title bar and menu bar is (0, 45) then SDL_GetWindowPosition() will insist on giving me the position I set rather than the actual position, that is until the user moves the window, then SDL_GetWindowPosition() will return valid positions. It's as if SDL doesn't check the actual window position after attempting to set it to the given values.

It happens with a fresh hg clone on macOS 10.14.1 with Xcode 10.1. The window is initialised with the flags SDL_WINDOW_OPENGL | SDL_WINDOW_RESIZABLE.

Tagging a bunch of bugs with "target-2.0.10" so we have a clear list of things to address before a 2.0.10 release.

Please note that "addressing" one of these bugs might mean deciding to defer on it until after 2.0.10, or resolving it as WONTFIX, etc. This is just here to tell us we should look at it carefully, and soon.

If you have new information or feedback on this issue, this is a good time to add it to the conversation, as we're likely to be paying attention to this specific report in the next few days/weeks.

Thanks!
