Current audacity-2.4.2 depends on wxGTK:3.0-gtk3, moreover it's the only packaged gtk3 wxGTK version. Release notes are not clear with exact minimum version, they made it clear in response to issue: https://github.com/audacity/audacity/issues/639
Release notes: https://www.audacityteam.org/audacity-2-4-2-released
For now wxGTK-3.1 can only be found in one overlay.
Someone noted in my issue, that wxGTK-3.1.4 is officially unstable, dev version.
As for that bug, it was for tracks redraw issue, which seems to be caused by using wxGTK gtk3 slots (I got redraw problem even with 2.3.2 when built against gtk3 wxGTK, while with gtk2 variant - no problems). Source for version 2.3.2 ebuild - just copied one from 2.3.3, editing patches list and wxGTK slot.

The same happens in BOINC Manager Disk Usage tab. See #650500
Whether updating to wxGTK-3.0.5 or 3.1.4 helps, remains to be seen. (Haven't tested that, yet.)

Tested, no difference. Although both wxGTK-3.0.5 and 3.1.4 work just fine, my problem with the BOINC Manager Disk Usage tab isn't effected.
Just a few more clarity on required versions, as stated on the official site: https://www.audacityteam.org/download/linux/
"Incorrectly built packages
Some distributions offer Audacity that was incorrectly built against the wrong wxWidgets (3.0.x). Audacity 2.4.2 must be built against wxWidgets 3.1.3."
Actually, it is a bigger mess: https://wiki.audacityteam.org/wiki/Building_On_Linux
"WxWidgets 3.1 built with gtk2. (see note below)
Audacity's fork of wxWidgets 3.1.3 (https://github.com/audacity/wxWidgets) should
be used as this includes bug fixes that are not yet available upstream.
WxWidgets should be built with gtk2 as gtk3 is not yet fully supported."
Given that media-sound/audacity-2.4.2-r1 is the only one in the tree and it is marked stable for some reason, I'd see we need to bring back some older version and/or at least mask 2.4.2 with ~arch.
