[Test Case]
1. Launch system settings dialog
2. xrotate portrait
3. Touch and hold on the dialog titlebar
4. Drag the dialog up and down the screen

Expected behavior: Dialog window moves smoothly across screen
Actual behavior: Dialog window occasionally flickers and jumps around the screen

[Discussion]
The window appears to jump some fixed amount when dragging, although the amount it jumps varies from one drag to the next. Primarily the jumps seem to be +X (rightward) jumps of ~200 pixels, although occasionally there will be larger +Y (downward) jumps of 300-400 pixels. If one of these downward jumps occurs when the dialog is partially off the bottom of the screen it can result in the entire window moving to the next workspace down.
