Selection changes to subtract mode after aligned moving cloned pixels
There's a very annoying bug with selection tools, which can be 100% reproduced and happens quite often for me. The reproduction steps are following:
- select Rectangle selection tool (any selection tool should work actually)
- select something
- press Shift + Alt and move mouse to copy pixels
- now, while still holding mouse button, hold Control and move cloned pixels, so they align to an axis
- while still holding Control, release the mouse button
Your selection tool now automagically switched to subtraction mode and you have to manually switch it back.
I'm using Windows if that matters, GIMP 2.10.2.
