GIMP 3.0.6 on Linux Mint 21.3 Cinnamon
Using the paint bucket tool, sections that were already filled change color.
I made an image with several sections that I want to fill with the paint bucket.
I filled several sections with red without a problem.
I start filling the next sections with pink (see settings below) When I fill the first empty section with pink, no problem. When I click the second empty section, it is filled with pink, but the first pink section changes to red. When I click the third section, the second changes to red as well. When I click the second section again, that one turns pink but the third one goes to red.
The sections are closed; there's no "leakage".
I tried closing and restarting the program, but that didn't change anything.
I hope this description makes sense. I wanted to attach a video but that didn't work.
Does anybody know why this happens and - more importantly - how to prevent this?
Foreground color: pink
Background color: white
Tool settings:
FG color: pink
BG color: white
Mode: normal
Fill type: FG color fill
Affected area: fill similar colors
Finding similar colors: Fill transparent areas
Threshold: 116,1
Fill by: composite
Thank you.

| Why does HTML/css scale images better than Gimp? |

Say I have a photo that is resolution 2000 x 1500. Now say I put it in a web page, and scale it using css to 600 x 400. NOW, say that I take that same 2000 x 1500 image and scale it down to 600 x 400 using Gimp or even Photoshop. If I take the second image, put it in a web page and display it at its 600 x 400 width, and compare it with the first larger image that was scaled using only css, the second one ALWAYS looks fuzzier. Also, the colors will often also look diminished.
So, my question is, why can't Gimp or Photoshop do as good of a job scaling images as HTML/css can?

| GIMP 3.x Python Plugin Issue: Reliable Program Exit and Image Closing |

Hello GIMP Community,
I am facing an issue in a GIMP 3.0 Python plugin: reliably closing the program and the last active image when the sequential workflow is finished.
My script is running in the GUI Mode, and I need to perform two actions in order:
- Close the last open image container.
- Force GIMP to quit the application entirely.
The old methods from v2 do not work anymore and I am unsure if what I am trying to achieve is actually possible.
Here is my script so far (German annotations):
Code:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import sys
import gi
gi.require_version('Gimp', '3.0')
gi.require_version('GimpUi', '3.0')

Does anyone have an idea whether what I am trying to do is possible?
