--- Comment #2 from V Stuart Foote <vstuart.fo...@utsa.edu> ---
Confirming on Windows 10 Home 64-bit en-US (1803) with
Version: 6.2.0.0.alpha0+ (x64)
Build ID: ce9fd6d1329ecf4ab1f710472fbf55fd4bf0058d
CPU threads: 4; OS: Windows 10.0; UI render: GL;
TinderBox: Win-x86_64@42, Branch:master, Time: 2018-09-21_23:53:25
Locale: en-US (en_US); Calc: threaded
But, believe there are two interrelated actions; 1.) recalculation of the nodes
relative to other elements of the formula, 2.) then scaling/stamping the glyph
into the element bounds for the node(s).
Recalculating--using the F9 or Update button--parses the entire formula.
Believe nodes with "scalable" brackets, especially composite nodes including
the OVER and SQRT notation, have a long present (StarOffice era) sequence flaw
in calculating the node in relation to other composite nodes of the formula.
That is very deep in the sm module.
Otherwise scaling/stamping the gylph into the node *is* affected by the
rendering mode--OpenGL via DirectWrite has more trouble with the
scaling/stamping compared to HA or CPU only Default rendering. The glyphs being
scaled and stamped in Default rendering are less volatile.
