We have noticed that when using Uperpan there can be periodic 'hicking' of the content during playback. The jumps can be very subtle and are most noticable with scrolling images. The timing between jumps is hardware dependant, but it is usually between one to several minutes.
Please note:
if you are noticing a constant jumping (On grasshoppers only) this is a different issue, and is most likely to do with screen assignments: please see below.
A patch has been developed to fix the periodic hicking issue. Please download and install the attached patch.
On the Grasshopper, it is very important to ensure that the output and engine screen assignments are correct. In the ATI control center: accessed by right-clicking on the desktop and selecting catalyst control center and selecting the manage displays option. Please make sure that the local zookeeper screen is one and is set to primary. This should have all of your folders and the windows task bar on it. Screen two should be the output screen and should not have any folders or windows on it.
