Thank you for the reply!
glsls version is 3.1,
I saw your post and tried executing the program with the "s" parameter and it indeed works correctly by doing so (the pixel options + export of preview work flawlessly btw).
A minor issue I found was that images of a certain attribute will not load. More than likely the size dimensions must be within a certain range. Images whose dimensions are larger than the program can handle (I experimented with a 1004 px width x 417 px height image) will not load. Not sure if there is a manual for this program, and if this is mentioned in there. But in case it isn't, this is just for your info (in case you didn't know already).
Lastly, I have attached a full report of my pc's specs below (apologies if its too long, but I didn't see an option to attach a file, so I only put the items I think are important):
Great stuff you have thus far!

hi! Thanks for the feedback!
Could you handle me some of the images that doesn't work? I've tried with images as big as 2048x2048 and worked in my pc. Have you tried in another machine to confirm it happens to you in other systems?
There is no manual yet, as i have really little free time, but surely there will be.
I'll try to look further into this,but i need to be able to reproduce this behaviour first
I haven't tested it in another system. I'll try to see if I can.
In the meantime, here is the image attached. When I try to load it, Laigter crashes. 
Edit: double-checked to see if downloading a copy of the image would work, but it didn't. Hopefully the behavior will be reproduced on your end.
Thanks!
I was able to test on a Windows 8 pc. Same problem. It seems that there is an issue with loading this type of file (maybe because of the dimensions, but it could be anything) for Windows 7 and 8.
Yes, the sprites have a black overlay but that was a preference since only the file loading needs to be tested.
Thanks!
There is an issue open for this.. Apparently also in some Windows 10 pc this happens.. But i couldnt reproduce it on any of the machi es ive tested. Toda i tryed in a win7 32 bit machine and worked... I hope someone can grab the cose and help me debug this.
Also, it seems that in different mchines the size that causes problems is different as other user reported. Someone suggested that it May be cause of Windows memory allocation system, because in Linux this doesnt happen.
Ill keep looking for a solution
Sorry for the inconvinient.
Works in linux pc:
