Black Ink 1.6.7: No Jiggling Letters

January 20th, 2017

Black Ink 1.6.7 is now available from the Black Ink home page, and is waiting for review by Apple on the Mac App Store.

A subtle usability issue that’s bothered me for years is Black Ink’s propensity to, in some instances, redraw the solved letters of a puzzle ever so slightly off from the previous location. This had the effect of causing some letters to appear to “jiggle” as you type in the answers for adjoining squares.

I finally figured out the cause of that problem, and fixed it along with a crashing bug affecting Touch Bar Macs, and a possible energy-saving change to prevent Black Ink using the unnecessarily powerful graphics card on some Macs:

  • Fix a problem where puzzle grid answers could shift slightly while solving
  • Add NSSupportsAutomaticGraphicsSwitching to Info.plist to depending on high power GPU
  • Workaround a bug that could cause Black Ink to crash when waking a Touch Bar Mac from sleep

Happy solving!
