Problem in how it shows my pdf

New Here ,

I don't know why, but every time I open a pdf file with Adobe Reader, it doesn't shows correctly, the file becomes weird, like a cromatic aberration. It disapears when i select the page, but when i touch it, for example to highlight a word or sentence, there it is again.

Because of that i have to find a new program, cuz this made it impossible to work.

If someone knows how to fix this, please help!

(The program is in Spanish cuz is my mother lenguage)
