I am running GIMP 3.0.4 on an iMac with Sequoia 15.6.1. The last major upgrade to GIMP (presumably to v.3.0.0) made a change to the controls such that all the sliders, mouse movements, etc became far more sensitive (i.e. a small mouse movement produces a huge change) and actually very difficult to work with.

This is particularly frustrating when trying to navigate around a large image by sliding a finger over the mouse.  The on-screen sliders work OK for navigation, but are far less convenient - and anyway, this all used to work fine in GIMP 2.

The slider scales for things like brush size seem now to be logarithmic.  That makes it (too) easy to make big changes to brush size, but really difficult to select small brush sizes (e.g. for spotting dust on scanned images using the clone tool).

I have dug about in the iMac system settings, and tried all possible combinations of the mouse controls, without any effect on GIMP.  It seems there must be a mis-communication between the OS and GIMP.

Any ideas for workarounds or fixes, please?

This week I noticed my system was crashing when I used GIMP. So I monitored it with the Missions Central application and discovered that GIMP was using 9.5GB, even though I wasn't doing much editing. Today I'm using GIMP 3.0.4 and Linux Mint. I noticed that just opening GIMP consumes about 5GB.
I managed to solve the problem as follows:

I went into the preferences section and made some changes to the system resources section, as follows:

Minimum number of undo levels: 10
Maximum undo memory: reduced to 1024MB
Fragment cache size: reduced to 1100MB
I left the other settings as they were.
This reduced RAM consumption during editing, but when opening GIMP it remains at 5GB.

For my current tasks, I haven't noticed any significant performance losses yet. Regarding GIMP opening with 5GB, although I'm not sure, I think it's due to having the following installed:
GMIC Plugin
Resynthesize Plugin
Remove BG Plugin
Several extra brushes
Thank you
My question, however, is this: is it normal to have this %GB consumption only when opening GIMP?
Are the settings I made in preferences relevant?
Here's my machine:
Acer Nitro 5 AN515-45
RAM: 16GB 3100MHz
Processor: AMD Rysen 7-5800h with integrated graphics
Dedicated graphics: RTX 3060

As I expected, installing open-source programs on Windows 11 isn't going smoothly. Gimp 2.10.38 - no (now installed as a portable), Mozilla Firefox - no (won't start, I'm now using Outlook), Mozilla Thunderbird - no (won't start, I'm using Opera, Google Chrome), etc. Gimp 3.0.4, LibreOffice 25.2, FreeCAD, and LibreCAD work fine.

On the other hand, installing Linux Mint on my old PC went smoothly. It feels like I'm using Windows.

The darker blemish in the lower right corner and the clump of hair that's curving toward the center: it looks weird. The browns need to be lightened to look like the rest of her hair and the whitish part probably need to be darkened a bit and perhaps tinted with a bit of yellow.

In Photoshop images are often sharpened using an iverted layer with blur. This gives much better results than unsharp Mask. Has anyone tried this method in Gimp?

Hello all,
I have a UV DTF printer that requires the print files to be setup in photoshop. I am a corel user and I do not want to get photoshop. I have GIMP on my machine but rarely if ever use it. Is it possible to have gimp do what is in the below videos what they are doing in photoshop? If so, would someone be able to screenshot or have a video or instructions on how to do that process in GIMP. Any help would be greatly appreciated.
Chris

Bonjour,
Merci de m'accepter sur ce forum


J'ai un soucis au niveau de la conversion du profil colorimétrique et je ne trouve pas où est le problème

Pour localiser : je pars d'un fichier raw en RGB profil colorimétrique attribué par nikon sur les NEF(RAW) Display 3, je passe par NX STUDIO(nikon) et je convertis le RAW en TIF adobe RGB 1998

Ensuite j'importe le fichier dans Gimp et je le retravaille . Une fois les retouches terminées j'exporte ce fichier TIF adobe RGB, pas de soucis. Mais si j'exporte ce fichier en JPG Adobe RGB il est enregistré avec le profil  sRVB IEC61966-2.1 et pas avec le profil de base adobe RGB

Et si je convertis le fichier TIF Adobe RGB avec un autre profil pour impression, et que je l'exporte la conversion est bien prise en compte. 
Mais si je veux exporter ce même fichier (avec un profil choisi) et en jpg , il va me l'enregistré avec le profil sRGB IEC61966-2.1 . Je ne comprends pas et je ne trouve pas la solution

J'aimerais pouvoir en format JPG exporter ce fichier avec le profil de base adobe RGB ou un profil choisi et pas qu'il me le convertisse en profil sRVB IEC61966-2.1

Merci à vous pour votre aide , 10 jours que je cherche, je n'ai pas trouvé. Je suis aller dans " settings gestions des couleurs " importation et exportation d'images ", " Image par défaut " j'ai essayé beaucoup de choses mais rien n"y fait

I'm having trouble converting the color profile and I can't figure out where the problem is

To give you some context: I start with a raw file in RGB color profile assigned by Nikon on NEF(RAW) Display 3, I use NX STUDIO (Nikon) and convert the RAW to TIF Adobe RGB 1998

Then I import the file into Gimp and rework it. Once I've finished editing, I export this Adobe RGB TIF file, no problem. But if I export this file as an Adobe RGB JPG, it is saved with the sRGB IEC61966-2.1 profile and not with the basic Adobe RGB profile

And if I convert the Adobe RGB TIF file with another profile for printing and export it, the conversion is taken into account. 
But if I want to export the same file (with a chosen profile) as a JPG, it will save it with the sRGB IEC61966-2.1 profile. I don't understand and I can't find the solution: (

I would like to be able to export this file in JPG format with the basic Adobe RGB profile or a chosen profile, and not have it converted to the sRGB IEC61966-2.1 profile

Thank you for your help. I've been searching for 10 days and haven't found anything. I went to “Color Management Settings,” “Import and Export Images,” “Default Image,” and tried many things, but nothing works

How do I resize an image to 5.000x7.000 inches?
I don't want 5.147x7.000 inches or 5.000x6.800 inches.
I want 5.000x7.000 inches.

Hi y'all! How do I straighten a line? It's not a path, so I can't use any of the path transforms. I can design a path, but that takes time. Is there a tool that can turn crooked lines into straight lines?

Example: the letters in "TANZANIA" look jagged after upscaling.
