This problem appears to be solved with a new update to Mac OS Sonoma (14.1.1).
The original R.app GUI (R 4.3.1 GUI) (not including the “hack” fix kindly
provided by Simon) now works like a charm. Deep sigh of relief all round.

Subject: How can I stop my R console and other R windows "flickering" after I
updated my Mac OS to Sonoma 14.0?
Dear All,
I updated my Apple Silicon M1 Pro MacBook from Ventura to Sonoma 14.0. I have
the latest version of R for Apple Silicon (4.3.1, "Beagle Scouts"). I also have
the latest version of XQuartz (2.8.5).
On Ventura, my R setup worked fine ("classic" R.app GUI using console and
script windows, not Rstudio or terminal). However, with Sonoma, when I try and
toggle between the R console and an R script, the windows transition at very
high speed between each other, making it nearly impossible to select either the
console or the script.
This "flickering" phenomenon lasts for ~ 10-15 seconds each time I change
windows between console and script, making the software nearly unusable.
Changing the screen refresh rate does not help.
The problem is specific for R.app and does not affect other software.
Any suggestions gratefully received. I have also posted this question to
stackoverflow.
Many thanks,
Desmond Smith
