minecraft-java-editiontechnical-issueswindows 8
I was playing Minecraft and tried to take a screenshot but pressed F11 and ever since, my window has been acting weird, not like the normal windows 8 window.
The restore/maximise button is grayed out and I can't just drag it to the top of my screen to make it bigger.
Unlike in the duplicate question, it did not return to normal when I closed out of Minecraft and reopened it. Is there any other way to fix this issue?
Let's look at what is happening: Minecraft is trying to do something which returns 0xc0000005.
In ntstatus.h, a list of error code definitions, 0xc0000005 is STATUS_ACCESS_VIOLATION.
MSDN - Analyze Crashes to Find Security Vulnerabilities in Your Apps reports:
Access violation exceptions (STATUS_ACCESS_VIOLATION) are generated by modern processors when a memory access caused by an instruction or program execution does not satisfy certain conditions defined by the processor architecture or memory management unit structures.
So, we now know that Minecraft does something that causes invalid memory access.
But, what exactly is Minecraft doing?
j org.lwjgl.opengl.WindowsContextImplementation.nCreate(Ljava/nio/ByteBuffer;Ljava/nio/IntBuffer;Ljava/nio/ByteBuffer;)Ljava/nio/ByteBuffer;+0
j org.lwjgl.opengl.WindowsContextImplementation.create(Lorg/lwjgl/opengl/PeerInfo;Ljava/nio/IntBuffer;Ljava/nio/ByteBuffer;)Ljava/nio/ByteBuffer;+10
j org.lwjgl.opengl.Context.<init>(Lorg/lwjgl/opengl/PeerInfo;Lorg/lwjgl/opengl/ContextAttribs;Lorg/lwjgl/opengl/Context;)V+104
j org.lwjgl.opengl.Display.create(Lorg/lwjgl/opengl/PixelFormat;Lorg/lwjgl/opengl/Drawable;Lorg/lwjgl/opengl/ContextAttribs;)V+88
Here we see, Minecraft tries to allocate an OpenGL Device Context buffer in memory.
The thread mentioned by Ben Blank has a different stack trace and thus is irrelevant.
We first have to get more knowledge about your memory, which you gave:
I noticed that the command that the minecraft.jar file is being run with says that it can have up to 1024mb of ram. I only have ~500mb of ram, so it would be referencing pointers in an unknown location. I also notice a gl issue, which I'm not really sure how to fix.
Given that low amount of memory, I'm going to guess that your graphics card uses 128 MB shared memory which means that it uses RAM memory to operate. I'm guessing that your Windows uses another 100 MB. There is only 250 MB of memory remaining for Minecraft, and your page file.
Minecraft uses from 512 MB to 1 GB, consider that playing Minecraft will cause disk trashing.
VM Arguments:
jvm_args: -Xms512m -Xmx1024m
So, now, where does the problem lie?
"so it would be referencing pointers in an unknown location" -- no. Just because you tell it it's allowed to use 1024 MB doesn't mean it ignores allocation errors when it runs out of space and creates invalid addresses out of thin air to reference. For all I know it wouldn't even matter, Windows would just give it space in the page file. - Matthew Read
This comment on the question is not 100% correct, there are exceptions that don't use the page file.
Exactly, OpenGL Device Context buffers must be in RAM; the solution is to buy more RAM.
I doubt if 1 GB will do the job given that Minecraft can use up to 1 GB; better to be safe than sorry and get 2 GB to avoid future problems. This also makes sure you don't experience disk trashing to the page file, which can have a great impact on the performance...
Or well, I could be all wrong and it could be a driver problem. But seriously, 512 MB isn't enough...
I suggest installing Optifine and seeing if that fixes the issue.
While I know that the issue isn't your PC not being powerful enough, its still worth a shot.

I had the same problem a few days ago.
Go into settings, then video settings and there should be an option that says like "start as maximized" (sorry I'm not at my computer right now so I don't know the exact wording). By selecting that option it should toggle to windowed mode. Now if you restart Minecraft you can change the window size.
You can also press F11 to go back into full screen mode but unless you started minecraft in windowed mode you won't be able to change the size if you go back to windowed mode.
