            Bug ID: 458857
           Summary: Using Select All or CTRL+A to select the background
                    layer and attempting to Copy or Paste it results in
                    Krita freezing and needing to be killed
           Product: krita
           Version: 5.1.0
          Platform: Microsoft Windows
                OS: Microsoft Windows
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: Tools/Selection
          Assignee: krita-bugs-n...@kde.org
          Reporter: sockmonkeym...@gmail.com
  Target Milestone: ---

SUMMARY
On a fresh installation of Windows 11 Pro, using Krita 5.1.0 64-bit downloaded
and installed using the installer from the website.
Attempting to Cut or Copy the starting layer (background) of a canvas causes
the program to freeze up and requires you to kill the process.

STEPS TO REPRODUCE
1. Open Krita
2. Create a new Canvas (From Clipboard or Blank)
3. Use CTRL+A or Select->Select All from the menu to select the "Background"
layer in its entirety
4. Use CTRL+C or CTRL+X or Edit->Cut or Edit->Copy
5. The program will stop responding indefinitely
6. Kill the program via task manager or clicking on it rapidly to bring up the
prompt asking if you want to kill the program

OBSERVED RESULT
Krita locks up and becomes unresponsive
When trying to paste into MS Paint it pops up the warning "The information on
the Clipboard can't be inserted into Paint."
The information on the clipboard also cannot be pasted into a text editor.
Windows+V to bring up the clipboard shows no entry.

EXPECTED RESULT
The background layer is copied or cut and can be pasted inside or outside of
Krita

ADDITIONAL INFORMATION
You can select smaller portions or select larger than the canvas size and it
will not crash when using Cut or Paste on the Background layer. You can also
create new layers and use Select All + Copy/Cut without causing a crash.

Not sure why it shows Windows 10 as my OS unless it doesn't detect Windows 11
info yet.

Attached a DxDiag output, Submit Bug Request text output, a recording
demonstrating the crash twice, and a recording demonstrating the info Krita
displays (saying Windows 10 for some reason) + crashing from displaying that
