Today my Soulseek client window has become so wide that it's almost unusable. I can see the border resize icon, but can only resize it for wider, as if a "minimal width" setting is in place. The height has no restraints. The window context menu has the Minimize option available, the Maximize is disabled. Selecting "Resize" from this menu is the same as with the mouse. When I double-click the title bar (which usually maximizes the window), nothing happens. I tried the "Reset Window and Column Size Settings" button in Options|UI, and even after restart the program and the computer, nothing happens. I found this similar issue, but no solution yet.
I'm using SoulseekQt build 2016.1.17 on Debian Jessie 64-bit, GNOME Version 3.14.1.
