[Details] g_idle_add () which was used for this purpose used G_PRIORITY_DEFAULT_IDLE>=200 which was too low for correct main menu requests processing, like showing Mixer or Big Clock Window.
The priority was increased to G_PRIORITY_HIGH_IDLE = 100.
According to GTK manual (https://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html#G-PRIORITY-HIGH-IDLE:CAPS)
GTK+ uses G_PRIORITY_HIGH_IDLE + 10 = 110 for resizing operations, and G_PRIORITY_HIGH_IDLE + 20 = 120 for redrawing operations.
I assume that during record or playback on tracks there are too many redraw request which didn't give any chance for main menu request to be processed in time with old priority value.
This change must be considered as a hot fix so far.
The issue might be deeper. Will be investigated with Paul.

CF reports occasional “rendering icon 1 at size 1 x 1”
always followed by “rendering icon 1 at size 21 x 21”.
Probably a GTK bug with some specific version of GTK.
- Also makes "Mod4" Appear as "Windows" and adds new combination
"Alt-Windows" to the dropdown.
- Attempt to set a pair of default snap modifiers (without
knowing what it actually is for OSX)
- Copy modifier now saves
- Snap modifier modifier problem still remains.
- Copy modifier still doesn't save
- Testers please edit the Extra section of ~/.ardourN/config to allow
defaults to "take"
- Note that the current defaults overlap.
- warning - absolute snap modifier has no default and will be always
"on" unless you set it!
Note that no defaults are set - go to prefs->user interaction to
ensure that nothing is set to "no modifer"
also - the copy modifier doesn't actually save its state yet.
- user can abs/rel modifier key in prefs->user interaction
suggested for linux - absolute->alt ignore snap->alt-shift
- Constrained mode works the same as button 2 drag (initial move
sets constraint axis).
