I haven’t seen an obvious solution to this and wanted to see what others have done to get around it (here’s the last conversation I saw around it: Monogame github issue
I am doing a network/multiplayer game and when a user drags the game window the Update/Draw methods pause until they release the window. This de-syncs the game from the server temporarily which is a problem for a serious multiplayer game.
I think I got a solution and feel silly because I linked right to it in my original post.
For anyone who search for this, just pull down the latest GitHub repo of Monogame, build it, and reference that DLL in your project. Someone already fixed the freezing problem and merged that code in.
It just hasn’t been formally released as a Monogame dot version yet since it was in December 2018.
