Image doesn't move smoothly

I decided to give gimp another go. I've updated my video and run an ok pc with decent stats but when I use gimp and try to move any image, of any size or resolution the image lags when i position it. even on simple single color layers. If i make a red box and try to move it the image is so choppy it looks like Im watching a picture download circa 1995.

Any idea? I don't have this problem when I run Pixlr and when I ran my demo of photoshop.

You should describe this in a way that gives others the chance to reproduce exactly what you got - assume that they know how to use GIMP, but do not know what commands you use.

By following your instructions, they should have the same image as you and be able to do the positioning just like you.

This is a screen shot of the issue. I had a 3500x3500 image I was putting together. I opened an image as a layer and when I move it around the screen it creates this lag. When I stop moving the image catches up. again this doesn't happen in other programs just gimp.

The only times I have seen the GIMP act like that (15+ years across /numerous/ machines and operating systmes) it was always a memory issue, typically due to working on a fairly huge image with many full size layers and LOTS of "undo" steps saved.

Fist check the size of the images you are working with, in pixels: This is shown in the canvas window title bar, after the name of the open file. If the X and Y dimensions are in the multiple thousands of pixels, that could be the problem.

I will guess that you are using GIMP 2.8, not a development build; if not, this may be incorrect (or not): Go to Edit > Preferences, and in the Environment menu (should be the one that opens by itself) and check the Tile Cache Size item. "When the amount of pixel data exceeds this limit, GIMP will start to swap tiles to disk." That sounds very much like what you are seeing when you move things around on the canvas. I normally like to set this limit to about half of total system RAM, more if the machine has a huge amount of memory, less if the system doesn't have memory to spare.

On my laptop which does not have a huge amount of memory, I start seeing a /small/ amount of lag when moving image-sized layers at about 2500 x 2500 pixels - noticeable, but does not slow my workflow down. At 4000 x 4000 pixels it gets more noticeable; I would have to adjust my maximum image size setting (same menu as above) to test at 4500 px or above...

Hopefully this will put you on the trail to a solution. If none of the above seems to apply, check all running processes on the machine to see if some background process is eating up a huge amount of system memory. poss8ible.

I run a dell with 8 gigs of ram and a 3.4 ghz i5 processor. it plays online games no problem and again doesn't have any issue with drag on pixlr. I have been working on 3500x3500 images on pixlr and I kept that file size for gimp 2 and it has issues.

Just tested on a 2400x2400 image and had the same issue. All i had on the page was a layer with a solid black box. I would move the layer and is was a mess.
