Today's update includes the following changes:

• Fixed a bug where the game rendered at the wrong size when running on a Mac with a Retina display configured to a non-default DPI.
  
• Added a setting to the in-game options to force the game to use the low-quality rendering pipeline (2K, not 4K). Most players shouldn't have to change this setting, but some players with high-DPI screens and underpowered GPUs (i.e. MacBooks) might want to try it out and see if the performance improvements are worth it.
  
• Changed the way that EXA windows are rendered so that the registers are still visible when the top of the window scrolls off-screen.
  
• Fixed some bugs with invalid hosts in custom puzzles.
  
• Fixed a bug where popped-out EXA and file windows could be dropped off-screen in a way that prevented you from picking them back up.
  
• Fixed a bug where the wrong window would receive the mouse click when two popped-out windows overlapped.
  
• Increased the size limit on the second KGOG puzzle from 100 to 150.
  
• Modified the test cases for the WorkHouse and final TWN puzzles to be more robust. They shouldn't be disruptive to most solutions, but histograms, leaderboards, and completion flags have been reset.
