It looks like you're playing in fullscreen with a resolution that's lower than your monitor's native resolution. The plugin currently uses the window size for the resolution, so all of the UI elements are rendered for your monitor's resolution (if fullscreen) but then they're scaled down. Think of scaling down a selection inside MS Paint and how you would lose pixels if you scaled down. I actually have a local fix for this in my own fork of the base plugin (not yet on my github fork, but will be eventually), but until I clean it up and do a release, you're probably best off playing at the same resolution for PSO as your monitor's native resolution, assuming you are using full screen. EDIT: It looks like you're using 2880x1800 or something for your monitor's resolution? So make sure in the launcher, you have that set for your resolution for PSO.
