I am on my surface pro 4 building from source. Clicking the gradient button on the scratchpad is crashing krita. Dr. Mingw doesn't have anything, I attached a debugger to Krita and this is the last step I could see before my QtCreator locked up. kis_scratch_pad.cpp: 489
I can confirm on Ubuntu. I had to reboot the OS since both Krita and the Desktop were locked.
Here on the 4.1 pre-alpha as well(master) I think dmitry may ave made a mistake when he was fixing the filter slowdown, because they both mention the sequential iterator: https://phabricator.kde.org/R37:907f88b9445e32425ddf384e4c99815b853bf680 Gonna assign him and release blocker to this because at the very least the scratchpad needs to have the gradient button hidden.
