[0.17.49] Freeze when using Alt+Tab

[giodueck]

So I usually listen to music on Spotify while playing, and I was listening to some new stuff, so I regularly used Alt+Tab to switch windows and see what the song was called.

When pressing Alt+Tab though, the game freezes for some time, maybe 10-20 seconds, and goes on fine after that. You can switch between what window you want, but just switching back to Factorio and effectively not even switching windows didn't help.

Hello, did it start to happen recently or was it like that in all 0.17 versions? (Or maybe even before 0.17?)

Does Alt+Tab freeze the game for you also in windowed mode? (Alt + Enter to toggle fullscreen)

Can you try to disable "Use flip presentation model" in graphics settings and restart the game?

It only started happening in .49, and after a few minutes in-game. No freeze directly after startup.

I couldn't get it to freeze with flip presentation switched off, so I think that fixes it. Thanks for pointing that feature out
