Something wrong is happening with my home-made presets in build X64_2.9.7.3 - it seems that they're exchanging settings with one another.

For example, I have a watercolour preset that works normally until I change the size, then I find that the opacity has inverted and the strokes are almost invisible. For some reason its opacity curve in the brush settings has changed completely.

Next I select an airbrush, and all is well until I resize it - and now the tilt has inverted. Looking at its settings I find that the X and Y Tilt curves have inherited the Size curve from the watercolour preset...

So I try selecting a marker and then the watercolour again and everything's back to normal... until I resize it, and now its Opacity curve has been replaced with the marker's Opacity > Speed curve!

Does any of this sound familiar? So far I haven't been able to reproduce it with any of the factory presets, which makes it a bit tricky to make a reliable bug report.

Hm, no -- it doesn't sound familiar to me, but maybe we can reproduce it if you could share your presets with us. Best make a bug report out of it, right now, the port to Qt5 and animation is pre-occupying our development time a bit.

Ok, it took some doing but I think I've managed to submit something that's reproducible.
