2257	Slow volume series playback with daily build, 2x faster with devel build	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Darwin-18.7.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-07-20)
Description
The ChimeraX daily build (July 26) plays the neutrophil volume series at 30 frames/second while my development build plays it at 60 frames per second.

The builds are using the same code, only the daily build is signed and uses MACOSX_DEPLOYMENT_TARGET=10.9 (before make install) while my devel build does not sign and sets no deployment target (my macOS 10.14).  Exchanging just the ChimeraX.app/Contents/MacOS/ChimeraX launcher (8 Kbytes unsigned, 16 Kbytes signed) which adds a few python command-line options (-I -m ChimeraX_main) makes the daily build run fast and the devel build slow.  So just the launcher alone is causing the slow behavior.

I used codesign --remove-signature on ChimeraX (reducing its size 16Kb to 8Kb) and the daily build remained slow.  So it is appears the culprit is the deployment target.  That needs testing.  Our download page says the macOS version is tested on macOS 10.12.
