Created attachment 103166 [details] Backtrace For crash: 1. Create new document 2. Create a new window 3. With the new window focused, move the pen to the first window. For hang: 1. Create a new window 2. Create new document in the first window 3. With the new window focused, draw on the first window using the pen. The on-canvas message "Group not editable" will appear and drawing will mostly stop working. 4. Close the first window. Krita is now unresponsive. Similar things to the hang situation will happen when both windows have a document. I think that I also had a cursor in one canvas only at some point, but I'm not able to figure out how to reproduce that. I suspect that this is bug 364984 and bug 371124
eek, fixed in https://commits.kde.org/krita/210a524c4515b32fe762a257d3f8a3a12eed7f2a -- and the rest of the bug is indeed a duplicate of 364984 *** This bug has been marked as a duplicate of bug 364984 ***
