Screenshot posting help!

Greetings,

I would like to help me on a matter of mine.
I am trying to develop a new game with Game Maker 8. It has a retro 2x scale graphical output, but on my PC it appears slightly distorted, as seen in my attachments.

I got a couple of nice, clean screenshots from the GM community, and thus I think its my PC only, or at least a small number of PCs where those graphics look glitched.

If you could please download the game .exe (it's 1,37 MB), run it, press F9 and upload a screenshot, you would be very helpful.

So, what does the game display look like on your system?

Well, um... yeah.
It sort of doesn't display at all.

Opps...

Sorry

This is a problem with Game Maker's surfaces; it's a dice roll whether they'll work on a particular machine. The solution is to use a less horrible game development program.

or make an output that doesn't produce such eyesoreness like any of those screenshots look like at least to me?

Well, no seizure-inducing grid, no test

Looks fine here, no scaling problems.

Hmmm...I have a Radeon HD4870. I can see no pattern at your screenshots. Maybe there's no guarrantee after all that the game will appear properly.

I will try to draw the screen in 1x, then draw onto a surface and then stretch 2x.

Here's mine

Yes, it's hard to scale an image to 200%. Done it before, took weeks.

That one has a diagonal line. Cool.

I get exactly the same as Razzorman.
