The problem is the WM_cursor_warp() function in editors/space_view3d/view3d_walk.c (and also in view3d_fly.c). The Wacom tablet works in absolute coordinate mode so warping the cursor to the center results wrong relative distances for the mouse events. I think the GHOST API needs a new function to check the possibility of warping - I don't think the GHOST internal check for this (window->GetTabletData()->Active != GHOST_kTabletModeNone) is usable here.

@Campbell Barton (campbellbarton), what's the status on this? I think the patch is good enough for now. It's hard to find good solutions for these things anyway :/

I really hope this goes in for 2.74. It’s impossible to use the tablet to control the camera...
