Title:
  Memory leak

Status in Ayatana Scrollbar:
  In Progress
Status in “overlay-scrollbar” package in Ubuntu:
  In Progress

Bug description:
  Attached is a small gtk test program which can be run in 2 ways:

  1) ./gtkbuildertest
  2) LIBOVERLAY_SCROLLBAR=0 ./gtkbuildertest

  
  in the first case, the memory increases over time
  in the second case, memory usage is constant

  valgrind gives me:
