I have 2 Macs. I know this is a per Mac issue.
When I click the Export Persona Button (3rd button from left), the whole top of the program turns gray and the icons turn blurry.
I click back on the Draw or Pixel Persona buttons and it is still gray with blurry icons. I tried to copy this issue on my MacBook Pro and no issue there!
What can I do to fix this...
iMac is 2009 with Yosemite, MacBook Pro is 2012 with Yosemite.
All updates current as of today. I have tried to check "Reduce Transparency" and uncheck "LCD font smoothing" but these do not help.
Also Yosemite seems to get the "blurry text" fever every so often, but that is an OS X issue i'm sure!
