GNOME Bugzilla – Bug 621078
DnD no effective in VNC environment
Last modified: 2012-01-03 03:11:17 UTC
drag and drop no effective in VNC environment.
For example, GTK+ MUA Sylpheed, able to drag mail from folder,
but unable to drop mail to other folder.
It occurs in only VNC environment, not plain X.
It is caused by below patch. It is included in 2.20.1 and later.
Yet another fix for shape handling
gtk+ 2.20.0 : DnD OK
gtk+ 2.20.0 applied it : DnD NG
gtk+ 2.20.1 : DnD NG
gtk+ 2.20.1 reverted it : DnD OK
I can confirm this behavior. It makes any GTK app (not just a gnome environment) very difficult to use over VNC.
I can also confirm that reverting this patch fixes the problem.
