[Gimp-developer] Slow, artifact-prone redraw when panning in 2.8.0-RC1

[Kurt Pruenner <leak gmx at>]

Hi,

I just downloaded Jernej Simončič's windows build of 2.8.0-RC1 and found
that both on my tablet running Windows 7 with Intel HD3000 graphics as
well as on my desktop, also running Windows 7 but with an ATI Radeon
5870, panning around an image looks really weird once you pan too fast:

A screenshot doesn't really do it justice, though, so I've also made a
~30 second screen capture video:

I'm just holding down the middle mouse button and panning the 100%
zoomed image around.

The same thing also happened using one of Partha's recent 2.7.x builds.

Does anyone else get similar results? Panning in 2.6.x was smooth as
butter for me... :/
