I just buy a new pc and install Ubuntu on it, and, obviously gmusicbrowser.
I use my personal layout (joined) with a little button on right bottom to open a new panel (with queue, lyrics, etc.).
When I use this fonctionnality, gmusicbrowser window become larger than my screen.
How tweak my layout to not become larger than my screen ?
I solved my problem, adding those settings : expand_max=400,ellipsize=end
in Title, Album and Artist widget.
