Magenta highlights vs raw clipping indicator vs filmic white level

Hardware is an i7 processor (several years old model), no video card (I use the built-in graphics), 32Gb memory.
I noticed this just today using today’s Master build 3.9.0+1484~gdc929e1f9

I did two different things when building today ! ?

  1. I did “sudo git config --global --add safe.directory /home/user/DT-top/DT-Mast-12May22/darktable-code” just before the cmake, this seemed a good idea in the light of
    dt unknown-version? ["solved" -- sort of] - #16 by pehar

  2. I copied my previous cache and config folders. That is, I ran up dt immediately after building with new folders; then quit dt; then copied the cache and config from previous 1st May build to be the new folders. When I ran dt there was a popup about updating the database, I did that, all seemed fine.

I’ll also mention that I quite commonly get a message like this in the Terminal window -
(darktable:6146): Gtk-CRITICAL **: 14:11:54.144: gtk_render_frame_gap: assertion ‘xy1_gap <= width’ failed

where the 6146 can be various numbers. I’ve not been able to spot what causes this.
