PS CS4 trouble random block artifacts appear after filling vector or path...

[AIRSPD]

I'm curious if I'm doing something wrong here or if there is a known bug at play.
When attempting to right click on the vector path in PS CS4 and selecting Fill Path, the path is filled as chosen but random block artifacts are created...
I tried to trick it by creating a vector mask and fill tool selected color and it works fine like in the third photo. As soon as you rasterize the layer, it goes back to the exact previous problem. The artifacts even show up in the layers mask icon.
Has anyone ever seen this before? It happens intermittently but frequently with filling vectors.




Thank you in advance for your time.

Hi, AIRSPD. I use CS4 and never experienced that. Have you tried resetting PS preference?.

I don't understand your problem, since the squares are caused by your mask. You must have had an active selection when you created that mask.

This happens randomly with multiple files. This isn't something that I have done that would carry over for a year to many different files.
My solution was to download CS6...
problem solved.
