Comment (by tcwan):

 The problem persists with gnucash at 5.4 and gtk3 at 3.24.38_0+x11.
 I downloaded the macOS build from gnucash.org which does not exhibit this
 behavior.
 However, I prefer the X11 version since I can access gnucash via a remote
 login, instead of having to log into the account from the welcome screen
 in macOS.

 The toolbar icons are not displayed correct at any time, but that can
 still be tolerated since they are not critical.
 The main tab in the window displays the background in white. Subsequent
 tabs will display the background in black (inverted). Clicking in a field
 in the tab views will show the proper background, but any mouse movement
 will revert to the black background.
 Unfortunately I could not screen-capture the case where the second tab
 displays normally, somehow it will always show it with the black
 background.
