A message from AVLinux (creator of AVL-MXe) on the MX Linux furum
explains that the removal of GTK2 from the next stable release of Debian
could affect the user interface display of certain plugins. He explains
the problem and the source of the solution he intends to use for AVL-MXe.
Will this problem affect the display of LV2 Plugin interfaces in
Cinelerra-GG?
well, because this is distribution-level decision ... I think it will depend on distribution users use? May be, like TDE gtk2 will be maintained separately (wishful thinking).
