Description Otto Urpelainen 2021-05-05 21:41:39 UTC

Description of problem:

When using Gnome on Wayland, right click empties the clipboard. Only happens when the clipboard was filled from different application than the target.

The clipboard still has its original content visible for other applications, and can be made work again for the Qt application as well by moving it out of focus and back in.
Version-Release number of selected component (if applicable):

How reproducible:

Always on Octave, KeePassXC and an artificial minimal reproducer

Steps to Reproduce:
1. Open a Qt 5 application, for example Octave
2. Copy some text to clipboard from another application
3. Paste it to the Qt 5 application with Ctrl-V, observe success
4. Right click on the Qt 5 application
5. Attempt Ctrl-V paste again

Actual results:
Nothing happens

Expected results:
Copied text is pasted to the Qt 5 application
