[R-SIG-Mac] How can I stop my R console and other R windows "flickering" after I updated my Mac OS to Sonoma 14.0?

[Simon Urbanek]

Desmond,

thanks for the report. There seem to be windows focus issue in Sonoma so I would not recommend upgrading at this point. Hopefully this will be fixed in a future macOS update (the .0 versions are notoriously flaky) - in the meantime I'll see if there is any work-around we could do in R.

Cheers,
Simon

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.
