GNOME Bugzilla – Bug 438325
Airbrush is not sensitive to mouse speed
Last modified: 2007-05-22 06:38:50 UTC
When using the airbrush tool, the stroke should have higher opacity when moving the mouse slowly than when moving it fast. However, this is not the case. No matter what speed you move the mouse, the stroke is exactly the same.
Try the ink tool.
Might depend on bug #347678, but I haven't checked the details.
This is unrelated to the ink tool, which varies its size with the speed of the mouse, not the opacity like the airbrush is supposed to.
The implementation is indeed pretty much broken. But if I remember correctly, it has always been. At some point Olof worked on a replacement but this work was never finished.
