Random sprite blurring?

[The_Sea_Four]

For some reason, some of the sprites in my game appear to be blurred, they are not being resized, and I actually have interpolation turned off. Looking at the code, they are drawn in the same way as the non-blurry sprites, so I have no idea what the cause could be.

Here is a quick before and after:

I had not updated GM for a while, and then I had to move to a new computer. I am using the exact same project files, but not getting the same result. I think it could be the result of an update I have missed, or my new operating system.

Well, I never did manage to solve this problem, but it could have been due to the fact that I failed to import the project properly after transferring it to my new computer, after exporting the old project and importing it, with no changes in my new computer, it worked perfectly fine. If anyone finds this and is having similar problems, it would seem that going to a previous backup is the only option.

I had this same issue and found this line of code to fix my problem; I hope it helps all of you <3

texture_set_interpolation(false);
