Up Topic Gosu / Gosu Exchange / Screen Flickering

I'm working on a game at the moment which allows the player to select between different resolutions. To change resolution, the Window is closed and re-initialized with the new resolution as would be expected.
It begins correctly, but 5 seconds in it starts to flicker to black very quickly, and stops drawing new frames. It does keep updating, however, and I can hear the game changing scenes when clicking around randomly.
I saw someone else post about this looking around, but I didn't find out how it can be fixed.

Anyone have any idea how to fix this? I don't want to ask the player to restart it themselves, or make a separate launcher.

Do you have newest version of Gosu? Similar bug was fixed around 0.8.x.
Also, system information may be helpful.

I just updated to 0.8.5 and it has improved slightly.
When I set the window to close, it creates a new window leaving the old instance open for a little while. While this phantom instance remains, all text renders correctly on the new window. When the phantom window closes (after about 5 seconds) all of the rendered text is drawn as white boxes. The game does continue running, drawing and responding.

I'm running Windows 7 x64, 4GB RAM, Ruby 1.9.3

I have filed a new issue on GitHub for adding Window#resize(w, h, fullscreen). This issue comes up very often, and closing windows to recreate them in a different resolution has never really been supported.

Not that this immediately helps you :) - I think the best way around this is a separate launcher, for now.

If this isn't possible at the moment, that's alright. I can work around it for now. It would be nice to have it working correctly at some stage, though - I'll keep an eye out for #resize in the future.
