[0.10.5] Windows Switch User Crash

[DaveMcW]

Windows 7 x64, Factorio version 0.10.5.

Steps to reproduce:
1. Start -> All Programs -> Factorio -> Factorio
2. Start -> Switch User
3. Click your username to log back in


When I'm on the main menu, I get this error message:

Sprite "C:/Program Files\Factorio\data\core|graphics\background-image-logo.png" couldn't be loaded

When a save is loaded, I get this error message:

This is annoying because my screen saver locks the computer by popping up the switch user screen. It has been happening since 0.9.8 at least.

Know Bug. At the moment no way to fix it. This also happens when the User Controll Window Pops Up.

IT also crashes when I hibernate/sleep the computer with the game opened.

Currently Factorio has nothing that loads the graphics back into your graphic card memory and when you pause your computer or switch the user your graphics card memory get cleared. The devs haven't found anything good to make this happen yet.

This is same or similar bug as reported here:

This is not true, Factorio needs to do that, or it would crash whenever you minimise/maximise it. The problem is, that some of the events aren't properly implemented in the graphics library (allergro), so we can't do it in these situations. It is one of the reasons why we offered cooperation (paid) to some allegro developer that would be able to fix these kind of problems, but no one who would be interested wasn't found.

This means, that I would have to dig deep into the allegro internals eventually and fix these things, but because it would be quite time consuming, I'm leaving the task for later now.

Moved to duplicates.

Still not working in 0.10.9, but the message when a save is loaded looks nicer:

Unable to create sprite (1440x900) probably not enough of video memory.
