Editing color of a gradient hatch breaks Undo

I have a peculiar repeatable bug:

When setting a hatch to radial reflected, and editing the outer color to a transparent color, after that undo is broken, also for commands run after this edit.

Hi @Gijs
That’s a weird bug indeed! Had the WIP open, and can confirm that it’s present in the WIP as well! :grimacing:

Checking it, thanks…

Got it thanks - this only happens, here, if History is on.

RH-71182 Hatch: editing breaks Undo

@Gijs , @Normand - can you repeat this at will? Here, we see weird things happening for sure but your original report seems to be only partly repeatable…

@pascal so far yes, but I will give it another try tomorrow. Maybe an additional comment: what I meant with transparent color is a color with transparency slider all the way to the left if that matters.
The steps I described above breaks it always. What are you seeing?

Hi Gijs - all kinds of stuff - initially, with History on, exactly what you report… however the developer was not able to repeat it from my descrioption and when put on the spot, I could not repeat it either - but we are seeing stupid stuff after some undos where for example two copies oh the hatch are left - one with endited color and one with the original. Whether or not this is a version of what you reported is still not clear but the developer, I think, feels it is all related and knows where to look.

@pascal yes indeed now I also saw that double hatch thing with undo.

To reproduce the undo break though:
Draw a shape and add a gradient hatch, and apply
Select the hatch and click Edit
Change center color to some other color (no alpha change), keep editing the hatch colors
Change outer color to some other color and reduce alpha coverage to 0:

Command: _Rectangle
1 closed curve added to selection.
Command: Hatch
Sorting... Press Esc to cancel
1 hatch added to selection.
1 hatch added to selection.

Great, thanks, I’ll try that routine.
