Public bug reported: I'm using the synergy software KVM to share a mouse and keyboard between two machines, with my Ubuntu workstation as the client. When attempting to drag-and-drop within Qt apps, the mouse cursor will freeze for several seconds. Cursor freezes also occur intermittently as well. I have an issue report for synergy as well: https://github.com/symless /synergy-core/issues/6487
This issue seems to be a regression related to update 1.6.4-3ubuntu0.2. The current workaround is to pin all libx11 packages to the previous (0.1) versions.
