Hello Memetkun,
I am sorry for the inconvenience, you might check out this thread -> Blurry Screen and something else.
a few steps you should do in order to fix that problem
update your GPU driver
set every settings to high and see if it makes any difference
update any possible driver you can think of that is no up to date, that could cause this ("Latest version of the .Net Framework, graphics card, Motherboard software, Direct X, and other things that you think.")
reinstall the game to another file location
a few question I/we need in order to help you
What settings do you have in PRO?
Was this issue always there or did it just appear?
Did you change anything in your GPU settings?
This was the latest staff response towards this issue ->
So in conclusion, if nothing helps from the thread I posted, someone from the staff team needs to teleport you back to a pokecenter (this might fix the problem).
