Additional copy and paste actions using the same Vector Selection results in non-updating image pastes. The resulting image will be the same as the first copy, despite moving the selection to a new location when copying. In order to bypass the non-updating pastes, while using the same 'Vector Selection,' one must select the 'Select Shapes Tool' and then activate the copy and paste command. The resulting paste will be a blank Vector layer. After this, select any selection tool, and then copy and paste. The new paste will reflect the new image that was copied. This sequence must be repeated for additional copy and pastes. Note: This bug affects the current stable Krita release as well. Instead of non-updating pastes, the pastes remain blank vector layers.
I have also tested Krita on my Windows 10 system, and can confirm the bug exists on the stable release as well.
Okay, found it. *** This bug has been marked as a duplicate of bug 385683 ***
