[3dprinter-general] Bug#949333: prusa-slicer: Black blobs around drop-down menu icons

[Simon John]

Package: prusa-slicer
Version: 2.1.1+dfsg-1
Severity: normal

Dear Maintainer,

Both the new prusa-slicer and the previous slic3r-prusa Debian packages have
had the same problem - the icons on the print settings/filament/printer drop-
down menu's on the right of the window have black squares around them - perhaps
the gear/colour/printer icons are PNG's with black backgrounds instead of
transparent alpha channels?

It doesn't happen with the upstream tarball installs (never has).

Lots of errors on the console such as:

(prusa-slicer:3518470): Gtk-CRITICAL **: 22:23:03.038:
gtk_widget_set_allocation: assertion '_gtk_widget_get_visible (widget) ||
_gtk_widget_is_toplevel (widget)' failed

-9 (allocation 1, extents 5x5) while allocating gadget (node button, owner
GtkToggleButton)

Also due to the use of GTK3's taller menu bar for plater/print
settings/filament settings/printer settings, in Expert mode the Estimated print
time is off the screen on the Debian build only.
