I switched to a Linux a couple of month ago (Mint 22.1/Cinnamon) and so far everything is going reasonably well. Coming from Win10 and doing a good deal of photo editing, the only fly in the ointment is that I have to give up on Affinity Photo (doesn't run under Wine for me, so still dual booting for that purpose). 

Naturally, I'm looking into GIMP as a replacement and I have installed the 3.0 RC3 flatpak. But there's a bit of a hiccup that bothers me to no end and keeps me from making a serious attempt at starting to learn the software: when I load an image and want to move it around with the Move tool, it is very slow (from dragging the mouse a small amount to the image jumping into position, it takes about 2 seconds). Other tools, like the paint brush or healing brush seem to work quick and without delay (AMD Ryzen 5700, 64 GB Ram, NVME drive).

I searched around for a solution and came across some posts discussing GIMP being slow, but none of that really applied to my situation. I tried uninstalling and re-installing the flatpak, and I played around with the Tile Cache Size (set it to 32 GB, half my system RAM), but all to no avail. The same image (a roughly 6000 x 4000 jpg) loaded into Krita can be moved around smoothly and without any delay.

Would appreciate any pointers what else to look into.

I'm thinking of getting a spare one in case.

I moved onto gimp 2.10.21 from an older version, where the tool panel was on the left only. The panel had all the features that the new one has on the right side.

Is there could be a new option added to path edit mode that enable path rotate ?

..i think if path move is available.. 

Then rotate function should be available  also , because both are curve transformations tool.

And it will be great addition also to determine and control the coordinates of the pivot of the rotation.

For the longest time my drag and drop hasn't been working in the layers. When I grab the layer it moves across the screen as it should but for whatever reason when i drop it just doesn't move. I have been having to move layers around using the arrows at the bottom of the panel but I cannot use layer groups because I can't drop and drop layers into the group. I have tried resetting to default as well reinstalling GIMP. 

Anyone else have this issue?

Hello,

I don't do much image editing in anything resembling robust software. Apologies in advance if I use terms that are incorrect (please feel free to correct me).

What I'm trying to accomplish - I routinely digitize archived paper documents that are oftentimes spiral bound or comb bound. I usually unbind these to get good scans. The problem is, the scans always show the edges of the paper and the holes left from binding. I would like to automate 'whiting out' the margins to erase these marks on the scans so I can get a cleaner scan for archiving. I want to retain the original image size so the contents of the document look like the original, including keeping original margins and whatnot.

I am using GIMP 2.10. I found the BIMP plugin and started messing with the features in that. It seems like automated a crop is pretty straight-foward with that plugin, but I don't see a way to retain the original image size. GIMP has options to retain the original image size when cropping an image. Crop may not be the right function to accomplish what I want, so any advice is appreciated.

Hi there, thanks for reading this!

I have an image (layer) in b&w  I want to use as a mask. In Photoshop, I used to make sure the layer is active and just press "strg+alt+2" or make a selection from the RBG or Green channel in one click. This gave me a selection that is hard in the bright white areas and softer in the areas where the light is less bright. I used this simple method to edit the highlights in my images with absolute precision, since I can paint on the b&w layer and exclude certain areas as well. It was so quick an easy and I was wondering if there is fast way to get the same selection out of gimp?

Thank you in advance

The problem is this.

When I try to open one of hundreds of images on my external drive and use Scroll, something really weird happens with the display. It only disappears when I hover my mouse over the file list.
Look at the screenshots.

The problem is even more obvious and annoying when I'm working on an image. Especially when I scroll or zoom...
Could someone explain how to fix this display bug?
Because it's really difficult to work comfortably.

Hello! I spent the last few hours adding an alpha channel and removing the bordering white from an image. When I exported in GIMP as a jpg, the end file still has the white. I do not know enough to tell if this is a jpg issue, a GIMP issue, or a user (me) issue.

If this is an issue with jpg files, how can I work around this, as I need jpg? I can try other image formats, but would prefer jpg because LibreOffice Writer doesn't like png format.

I am using GIMP 2.10.38 on Windows 11.

Attached is the exported jpg file. I can't seem to be able to attach a second image, so I will attempt to reply with that.
