ASSERT: "!this->isEmpty()" in file ../../include/QtCore/../../src/corelib/tools/qstack.h, line 56
I am not sure if this is due to the intel device, or due the layerstack changes.
To reproduce: make a selection with the path tool, or freehand path. Doesn't always occur.
I got a random crash on Windows when making a selection recently, I bet it is due to the same issue.
I didn't on the intel laptop, but suddenly, I seem to have something on my desktop that seems to be the same problem:

Okay, that's definitely not display driver related, must be something with layer handling, so let's ping dmitry about it.
I'm wondering how "Creation of a selection" can remove nodes? As far as I know it can only add a selection mask. It can also remove it (Deselect) if you just click on the canvas. But still I cannot reproduce the bug :(
This is probably fixed since then -- the code at line 343 doesn't look like this anymore.
