Description soitismyankh 2022-08-24 12:11:12 UTC
STEPS TO REPRODUCE
1.  Create new document with background as canvas color and one layer
2.  Draw anything on a layer
3.  Select anything on this layer and copy it via ctrl+shift+C
4. Paste it into MS Paint or Telegram via ctrl+V

OBSERVED RESULT
Krita will stop responding, MS Paint or Telegram will stop responding too.

EXPECTED RESULT
The copied region will be pasted as normal.

SOFTWARE/OS VERSIONS
Windows:  10

ADDITIONAL INFO:
After killing Krita via task manager, MS Paint will again start responding and will display a window with "The information on the Clipboard can't be inserted into Paint." text.

I've played with it a bit more and apparently it freezes both applications when copying via Ctrl+A - Ctrl+Shift+C, but when I copy small regions, it's pasting just fine.

Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.

I could not reproduce this on Windows 11 with Krita 5.1.0 and MS Paint. I saw in your screenshot that you had the recorder on, but if I do that, still no problems.
Comment 6 chloe.peiying.lin 2022-09-13 01:24:35 UTC
I also get this bug on Linux Mint 5.15.0
Comment 7 amyspark 2022-09-13 12:50:56 UTC
Switching to confirmed because multiple people have reported a similar issue.

Fix a crash when trying to copy-paste the background layer

Such layers usually have non-transparent default pixel, which
automatically needs an image for exact bounds calculation, which
doesn't exist for the detached layers.

The patch saves the copied area bounds on the construction
of mime data, much before the layers become detached.
