Apple fixed the GUI bug present in some of its Retina-Optimized instruments and plugins in LPX 10.3.2. For those who took notice, some of the stock Logic Pro X instruments and plugins produced an annoying graphical bug in regards to the number entry field when placed on any scale factor other than 100%.
Some of the plugins affected by this issue included: Retro Synth (in the screenshot above), Vintage B3, Vintage Clav, Vintage Electric Piano, Drum Kit Designer, Compressor, Channel EQ, Linear Phase EQ.
In the past: The blue halo that appears around the number entry field was distorted and out of place. That issue has now been resolved. The blue halo that appears around number entry field now complies with the scale factor of the plugin. Rock on Apple!
