Clipboard brush bug in 2.10.x/34 and in 2.99.14
Environment/Versions
- GIMP version: 2.10.34 and 2.99.14
- 2.99.14 is a flatpak from official gimp.org
- 2.10.34 one is a PPA from Panda Jim on Ubuntu-MATE 20.04.5
- 2.10.34 the other one is from Debian 11 (Bullseye)'s package on MX Linux 21.3
Description of the bug
Creating a brush that we put in the clipboard with some dynamics, here Angle X Fade
and for example those settings
We will systematically have black lines at the edge of the transparency It get even worse if we change the default size of the brush using the "Size" slider for a smaller or bigger brush
Here an example with the same brush where I use the size slider to make a smaller brush
You can see the black lines are getting worse
We have the very same bug on GIMP 2.99.34, but there is something even worse happening, the "Copy" (to clipboard) will copy all the 1024 pixels thus we do get now a square of 1024 px, thus the pointer is deported from the cross AND it does not respect the Spacing" of 1 at the 1024 px "original" size (after copy to clipboard)
=========================================
Also for the very same setting than in 2.10 the behavior of the dynamics is just "crasy" in 2.99.14 it does not rotate on itself to create a "rope" twisting alike, like in GIMP 2.10, but do something completely out of control
=========================================
2.10.34 video from the brush creation to end result
2.99.34 video same as above but for 2.99.14 and doing things "out of control"
