Gimp 2.8 and Windows 7 64-bit refresh problems

Gimp 2.8 and Windows 7 64-bit refresh problems
When I move anything around, the canvas (or whatever I am moving) starts to tear (the rendering of the canvas tears up). The movements also start to lag quite a bit. The canvas takes about half a second to refresh properly (i.e. the tears start to disappear).

Attached is a screenshot of a torn canvas while moving it around.

I have tried this on 3 PCs so far. Two PCs have ATI cards and the third PC has an NVIDIA card. I have updated the graphics card drivers (does Gimp 2.8 use the GPU to draw the canvas?)

Hi, I have the same problems. When I move a layer, the image doesn't move smoothly but jerky.
I have Windows 7 64 bit with an ATI card (HD 7470M), but I don't know the version of Driver and CCC. Have you which driver version?
Sorry for my english, greetings from Italy!

I am currently on a laptop with NVIDIA GTX 560M with latest drivers installed and seeing the same exact issue.

Perhaps the GPU acceleration (if enabled) is to blame? If yes, can someone let me know how to turn it off (or on, if it is off be default)

It looks like this is a general issue (among other issues - slow brush strokes, disappearing UI which I have started experiencing even on very small canvases) that make Gimp 2.8 nearly unusable for Windows users. I hope the developers are able to fix this soon.

I am seeing this as well. This must be a bug that came into GIMP in version 2.8
2.6 did not have this problem
I am on win7 64bit
I can still work with it but when I am doing an elaborate selection on a large image, it is very frustrating.
Hope the dev team look into this bug in the next release.

otherwise GIMP is Great!

The link below may provided a fix for the problems. I'm running vista and gimp 2.8.2.

As an update to the bug fix if No Colour Management is selected in preferences then this seems to solve the problem on a permanent basis.

RE: Gimp 2.8 and Windows 7 64-bit refresh problems
I want to add my weight to this as well.
I am a semi professional graphics editor and work with small and large images.
Since upgrading from 2.6.x to 2.8.0 the problem of a lag or tearing or jummpy panning has come into GIMP.
I have now been putting up with this for months and today upgraded to 2.8.2.
Seems this problem was not addressed in this version.
Now since pann and select is a very common task in GIMP, this bug really is a downer and probably discourages most people from switching to GIMP.

Not to be a complete downer, I want to add that I don't know where I would be without GIMP. It is otherwise a solid piece of production SW that myself and I am sure many out there could not live without.

Pleeeease, we are suffering in silence.
To the dev gods of GIMP - please give us feedback on this one

There are no Gimp developers on this forum. For problem like this, go to bugzilla.gnome.org. add yourself to the interested parties of the relevant bug reports. This tells the developers how pervasive the problem his, and raises its likelihood of being fixed.
