Screen turns to magenta/purple
When I play the game, after some random time the whole screen turns purple/magenta. There doesn't seem to be any rule on when it does. (Probably in dark areas?) There was one exception, when I was in a cave, and the ambiant (light around entities) effect caused some portion of the screen in pixellated circles, as if the scaled sprites were displayed incorrectly.

I start the game from BigPicture (so I can use the guide button on my controller) with 1600x900 resolution and run it in the default graphics settings. I use Windows 7 Core I5 & ATI video card (I don't know which one) and this is an HP notebook.

Does anybody else having this issue? I don't really want to blindly poking around, and also seems that changing the graphics on the go doesn't work very well.

Screenshots please
I have a few thoughts on the cause

Magenta is typically used as a color for uninitialized/unloadable textures and for other technical purposes. I'll put a wild guess out there: possibly not enough video RAM?

playing with 1,99 RAM
He must be running Windows ME or 2000 for it not to have enough bought from a store shelf

Video RAM and system RAM are not the same things. When rendering, extensive amounts of video RAM is used because that's where all the textures are loaded to. OP has specified neither amounts, and depending on the computer's configuration and how old it is, there may not be enough.

I have 12gb RAM, and found out that I have AMD Radeon HD 8750M/Intel HD Graphics 4600 (drivers installed), with 4292MB VRAM.

Yes, I wanted to provide screenshots though I took none. Instinctively I've always tried to solve it instead of taking a screenshot. Though not much to see on it. one solid color, not even the menu nor the hud are displayed then afterwards. Not even the main menu, until I either restart the game, or do the workaround described below. The only exception when the menu was visible, when not the whole screen was one solid color.

One possible workaround I found and worked for me that if I press alt+tab and then switch back. It even lasts longer that way.

I'd put my bet on the not enough VRAM, to have both the game and Steam BigPicture (and Aurora as well?) running.
Alternativeley, I shouldn't make my laptop work so hard, to run several other apps while playing, like Firefox with 5~15 tabs, Outlook, etc (about 5 of them?). I tend to overload my PC's, and never been able to resolve that tendency.

I'll try to take a screenshot and post it here as well. (I'm sure I can figure out how it is done.)

Are you running the game fullscreen? If so, try running it windowed and leave it windowed, then see if the problem comes back.

I played it for a while in windowed mode, and at 1024x768 screen size, so the game fits on my screen. Nothing special happend. Afterward, I've turned it back fullscreen and 1600x900 screen size and worked. I don't know what triggers it, though.

The next day when I've played it in fullscreen @1600x900 resolution, it went purple again, but this time, I made a screenshot: http://steamcommunity.com/sharedfiles/filedetails/?id=309481274

On a second look, it kind of reminds me of the default color on an XNA 4.0 project, that doesn't draw anything on the screen (not even clearing it). That version of that library always clear the screen with a simmilar color.

Edit: I have a feeling, that Flash (YouTube) causes it. I forgot to close my browser the last time as well.

That doesn't look quite like cornflower blue...
jadaml Sep 3, 2014 @ 4:07pm 
No, no. If you create a new XNA 4.0 project, and even remove the line that fills the screen with cornflower blue and leave the overriden draw method blank, then it will look like this. XNA 4.0 clears the screen with this color even if there's nothing drawn. In earlier XNA 3.5 this wasn't the case.

I was surprised when I was messing around in an XNA 4.0 project.
