Hi!. Im currently working in a three monitor setup. Handy. The problem i have with Gimp is that for some reason it starts each time where he wants. I want it starts in the main monitor, at center of the three. It is the main monitor on windows setup. But Gimp sometimes starts at right monitor, sometimes at middle, sometimes at left... Funny! But bother a little, you need to drag it, maximize, etc, before start to work.
I have changed preference in "Windows management" but no change. It still opens where it desires.
Any tip?
Edit: I found what happens. Gimp follows my mouse. If i move my mouse to another monitor after click GIMP icon, gimp opens where my mouse is placed. So... you need to waaaait gimp totally open, to continue working...

Hi, I would like to know how to copy the content of colors channels RGB (Red, Green and Blue) into Green, then copy the content of Alpha channel into Red ?

I tried it on PS and it was quite easy, but I can't manage to reproduce it on Gimp.

Thanks and have a good day !

I noticed this forum was down for awhile today. These errors are quite common and are mostly mysql database errors. From memory they usually mean stopping and re-starting the database but they need expert attention. Congratulations to the admins at Gimp-Forum

Hi Gimp forums,

I used to use GIMP 2.10, and recently updated to GIMP 3.0.6 to use the non-destructive editing for text effects.

My work often involves creating many sub-projects, and then compositing them together into one larger project. Keeping the sub-projects intact allows me to alter elements after importing to adjust the overall composition.

Naturally, when opening a project as layers, any elements outside the sub-project's canvas are no longer clipped off, due to the main project having a larger canvas.

For this reason, I started making the root layer of each sub-project a layer group, and using a layer mask to make only the parts within each sub-project's canvas visible when imported into the main project.

Normally, this works phenomenally.

However, when I tried to use NDE text effects in a sub-project today, I found that the presence of effects causes layer masks to not be imported when opening a project as layers.

At the moment, I can just merge down the effects before saving the sub-projects, but I would greatly prefer to keep these effects intact and editable.

The layer group I import each sub-project into has a layer mask of the same size, so the layer mask in the sub-project is more for the ease of lining up their boundaries. I could simply add a layer to each sub-project that paints a bounding box in black outside the canvas, thus making the sub-project's layer mask unnecessary. But making such an edit to all my sub-projects when I've been using a template with the layer mask already applied for a long time now feels like alot of tedious work.

I wanted to ask around if this was a known issue, perhaps one that has already been addressed in a development build, or if this is due to some limitation of how effect filters, masks, and open as layers interact, as well as any other potential workarounds.

Here's one of the sub-projects


Here's the result when effects are active. Notice that the layer mask on "Pokemon LeafGreen.xcf" is missing


Here's the result when the effects are merged down before saving and opening as layers. Notice that the sub-project is clipped at the bottom where the original sub-project's canvas boundary ended


Any input, verification of this issue, anything, is greatly appreciated. Thanks!

Hello everyone, I have used GIMP for a few years to make content for my Sims 2 game.

I had the plugin 'Layer via Copy/Cut' by Slybug and was very happy with it, on GIMP 2.8.

However, now I have GiIMP 3.0, and apparently cannot use the same plugin.

Does anyone know if there is an equivalent for GIMP 3.0 please?

I desperately want to morph some photos, a thing I used to enjoy doing in Windows programs.

I DLed GIMP 2.99 but nothing seems to happen when I tried to upgrade from 2.10

Hi. Working on some photo retouching i found usefull to clone some details from other pictures, elements from background, textures, etc. Usually i navigate that stored photos trough some external program, like could be xnview. Would be interesting be able to "clone" from any portion of the screens you have, instead to open the file in Gimp.
just saying...

Hi!. Im having issues with the option "expand layer" activated with clone, and maybe others. Anyone?
Two questions: how i report a Bug properly? 
and... there is some way to recover not saved works?
I save always but, since i had some unexpecteded crash too offenly, i wonder that myself.

Greetings. 

For a very long time, I used GIMP 2.10.2. The program worked very ok for my needs but needed to migrate to 3.0.2

The issue here is the fact, I use a lot "Exchange color" feature from Color tab. When I have a selected square from whole picture, I try to use this feature on GIMP v3.0.2. 
First time color has been selected to change, it nothing happens.

I try a second time to select a new color to be used and program crashes. Very frustrating.
This behavior does not happen at all in GIMP 2.10.2. At the very least, it takes some seconds to "load" and new color is assigned.

I'd appreciate your help to fix this crash, in case it exists. Video recorded is on link below. Thanks in advance
