Factorio Forums

Windows 10, locking the OS with Win+L caused the screen to freeze on whatever frame it was on. The game is still functioning perfectly fine in the background, I was even able to click on where the exit button is supposed to be and it exits just fine.

Things I have tried to replicate this with and succeeded:

-> Windowed mode
-> Full-screen (Is the full-screen mode just borderless-windowed? seems like it)

Asked others to try on the discord and didn't freeze for them, just me so I guess it's not really a bug but something to do on my end, are there any logs I can look at? Since the game process itself never freezes just the frame it is on.

Edit: I've tried resizing the window while frozen but it doesn't end the freeze at all, the screen stays as-is and the new area just stays black, I can get a screenshot.

Edit 2: Tried to switch to Windowed mode and it told me:

---------------------------
Error
---------------------------
Unable to create sprite (1280X800) probably not enough of video memory.
---------------------------
OK
---------------------------

Edit 3: Game also freezes when changing between fullscreen and windowed, oh boy.

Getting the same issue as you on 0.15.3 when going from fullscreen to windowed or vice-versa (Either the "Unable to create sprite (xxx) probably not enough of video memory" or else just a locked game). My game also locks up in fullcreen if I switch off my second screen whilst playing. Running a GTX1070 so pretty sure I have "enough of video memory"!

Logs & W10 version below.

Does your system perchance have both an on-board video card as well as the GTX?

Devs,
a few Google-Foo finds that may help:

If you compile a version with the d3d debug enabled (or if a debug d3d driver needs to be installed on my end, let me know), I'll be glad to run it and attempt to make it crash to help track it down as I have been getting this issue intermittently as well since .11 viewtopic.php?f=48&t=16063

Thanks for the offer. We don't plan to work on this issue anymore for time being. It is possible we will migrate from D3D9 to D3D11 in following months, so we would resolve corner cases like this one after that is done.
As a workaround you can set launch options in Factorio properties in Steam library to or set force-opengl=true in config.ini if you don't use Steam version.
