Problems with displaying graphics on a PC

Greetings, I have a problem with the fact that

I drew a Sprite in the application peint.net , added it to the game.

But when running a project on a computer, I encounter this.

Before launching the layout:

When starting the layout (preview):

You may notice that the sprite itself does not lose clarity, but color spots appear.

I also launched the project using a smartphone. There the sprite is intact and displayed correctly.

I also added this sprite in construct 2, everything is also correctly displayed there.

I ask for help or advice from everyone

Make sure your fullscreen mode setting is set to letterbox integer scale in your project properties.

Could you show me exactly where it needs to be done and show me an example of how it should be?
