Fix Version/s: None
0.4.6RC1 is affected.
The bug is very old, I noted it the first time in my ros 0.4.1rls tests.
When you install GsView 5.0 from rapps, the copy-progress is visualized via a listview.
Seems like there are some heavy redraw loops involved then, because it takes minutes on ros to install that tool and only seconds on windows.
The more the ListView is filled, the more severe the delay becomes.
gsview.webm shows only part of the setup to not bore you to death.
ros generates no log output during that.
ListView? Scrollbars? Win32SS?
