@Telesto : where exactly should I be looking in the time profile ?

On Mac Silicon M1, using 
Version: 7.0.3.1
Build ID: d7547858d014d4cf69878db179d326fc3483e082
CPU threads: 8; OS: Mac OS X 10.16; UI render: default; VCL: osx
Locale: fr-FR (fr_FR.UTF-8); Langue IHM : fr-FR
Calc: threaded

I see a faire amount of time is spent in what I assume is the render operation
:

223 ms

ripc_RenderImage CoreGraphics

and more specifically in:

vPremultipliedAlphaBlendWithPermute_RGBA8888_CV_sse4

but is this where I should actually be looking ?

I guess the SSE instruction set execution is the slow point here ?


However, in the grand scheme of things, at least from my perspective when
viewing the text animation, the animation occurs at a perfectly acceptable
speed.


Sorry I can't help more, as I don't really know which bottleneck I'm supposed
to be searching for. There are other bottlenecks which take up more time
overall, for example in the NSViewBackingLayer loop.
