What happened?

When I take a screenshot on the Mac (client) using control+shift+command+4 and then try to paste it with ctrl+v on the Windows (server) I get following issues on

Slack (via Chrome)
GMail (via Chrome)
Photopea (via Chrome)
https://evercoder.github.io/clipboard-inspector/ (via Chrome)
Discord, Skype - nothing happens on paste
win+v - there is no entry of the copied image

Surprisingly I can paste the picture successfully to MS Paint so I know that the clipboard data is being synchronized but is somehow corrupted or incompatible. I also don't have this issue when pasting the image the other way around; from Windows to Mac.

Version

v2.4.0

@widget- commented on GitHub (Jun 23, 2023):

Behavior is also inconsistent between screenshot types. If in Edge I use Web Capture (Cmd+Shift+S) and copy the entire page, I can paste into mspaint, then copy from mspaint and it's fine. Selecting an area results in a corrupted image.

But if I do a section or if I use the system-wide screenshot (Ctrl+Cmd+Shift+4) then it will look like this:

(This is supposed to be white text on a dark grey background, with a 🤯 (exploding head) emoji.)
