anyone? this is driving me crazy. can't use pen to navigate around images with hand tool. something i need to do quite frequently. which right now requires dropping the pen and switching to mouse which kills any kind of flow to working fast.
I have the exact same issue and it's extremely annoying. I just can't move around the image at all with a pen. Zooming in and out sorta works, but it never zooms in where you want to and so on.
To describe my issue: When hand tool is activated and I start dragging the pen on Wacom Intuos 3 table the hand icon does not change to "grabbing hand", picture moves maybe 5 pixels and then just gets stuck. If I now switch over to my mouse, click and drag, the hand icon "grabs" and picture moves very smoothly around.
This never happened with Lightroom 3.6 but started immediately after upgrading to Lightroom CC 2015. I'm on Windows 7, latest Wacom drivers (the second to latest had the same issue).
Hey, found a solution! Just disable the GPU acceleration and it works again.
GPU acceleration has been a real pain for me overall. Everything was slow, jittery and lagging. As soon as I realized to turn it off things got back nearly to LR 3.6 speeds and the software is usable again. Aye!
