GNOME Bugzilla – Bug 591017
Tablet pan is not working as fast as it should
Last modified: 2009-08-14 05:11:49 UTC
Please describe the problem: When i use my pen tablet(wacom bamboo), and i pan around an image on GIMP, using one of the buttons of the pencil, and i move it, it pans rather slow, not like the mouse does. Steps to reproduce: 1.Open GIMP with Tablet plug in 2.Pan Around with the pencil button Actual results: The panning is very slow, when you use the mouse(three click mouses) works a lot faster Expected results: It should be more responsive Does this happen every time? Yes Other information:
The problem is most likely caused by the fact that tablets send a lot more motion events than a mouse. Might make sense to use event-compression for panning. That would likely solve this problem. It would still be interesting to know what platform you are experiencing this on. Please specify the operating system.

Sven, without opening another bug report, can i ask if this fixes a trouble i notice too, selecting a complex brush and make it a BIG(using the scale dialog) makes also a big lag when you only move the cursor around, happens with mouse BUT with tablet the thing is just unusable(and GIMP can become unresponsive!) i'm using Windows right now and cannot test it on my other linux pc.
Hi Dan, no, please open new bug reports for new issues.
