Hi,

I have recently found that when I scale down an image, Gimp stalls, becomes unresponsive and then I have to close it down.

Example of image size is 7360 x 4912 (9.13 MB) scaling down to 1080 x 1080. I've been using Gimp your the past 3 + years and have never come across this issue until recently. It's not my machine, everything works perfect in Inkscape etc...

Version 2.10.30 (downloaded from gimp.org)

Machine: PC Specialist, Windows 11 Pro, 16GB ram, 1TB SSD, Intel Core i7 11th generation, intel iRIS Xe graphics card.

Any help would be much appreciated ?

9.3MB must be the JPEG file, not the image in RAM, which is more like 300MB once loaded (and likely over a gigabyte in high precision). Inkscape needs 24bytes per anchor in a path, so you would need a very complicated image to use 1MB for image data in Inkscape.

You can have a look at your process monitor (possibly a "Resources" tab) to see how much memory is in use when Gimp crashes.

Image precision and interpolation algorithm can also have an influence.

Might be a third party software, I came recently to this thread > https://www.gimp-forum.net/Thread-Can-t-...yers-fixed some people on windows got problem with GIMP while a third party software was opened.
Did you installed something recently?

Totally different thing, in the case you mention these are utilities interfering with the mouse events. The OP's problem is a plain old crash when the application does heavy computing.

Hi all,

Thanks for all your replies, really appreciated it.

The problem only exists when I am downscaling very large images, so I now do this in Microsoft Paint of all things and it's done perfectly in a split second, so it seems it's defo some glitch with Gimp!

If this issue continues you may want to lodge a bug report here https://docs.gimp.org/2.10/en/gimp-bug-report.html
I don't work with images that large and do not have that problem. however people at https://pixls.us/ may, and they might beable to give you an inkling as to what is going on.

The problem really needs to be reproducible for sending off to the devs as a bug. Just tried a 7360x4912 jpeg (about 8 Mb file size) > 1080x1080 without a crash.

1) This laptop Linux kubuntu 20.04 Gimp 2.10.30 16 GB memory 500 GB ssd intel i5 intel graphics - using interpolation No-Halo and no crash

2) A Win 10 VM Gimp 2.10.30 a more modest 4 GB memory - using cubic interpolation this time - no crash.

Very easy to blame Gimp but more probably a local problem. Running out of resources. A hardware issue. Some user setting in the User profile.

Always useful to disable the Gimp profile and let Gimp make a default, then see if the problem re-occurs. Same with the image, try a different image (same size and format, although it seems all your large images ?) Open one image only, not multiple. Keep it simple. It is all about ruling out possibilities.

I have exactly the same issue using Gimp 2.10.30 on Windows 11 Home 64-bit with 16Gb of memory. These images are not that big, under 3000x3000 and RAM usage hardly increases at all.

It only freezes up though if I have done a crop to selection first. I can scale the entire image first, and then crop to the proportions I want, and that works fine.
