Hello @bman, thank you for reporting!
I’ve been trying to reproduce this issue to no avail. I’ve tried it as follows:
- I’ve taken a screenshot that saves it to the clipboard with the macOS integrated screenshot tool. That’s with Ctrl+Shift+Command+3.
- Then I’ve pasted (Command+V) the screenshot into Sketch’s Canvas.
I’ve tried both 2025.3 and 2025.3.1, as well as Sequoia and Tahoe, but I haven’t been able to reproduce the behaviour you’re describing.
Is there anything you did differently from my steps? Could you please let me know if you’re using a specific tool to take screenshots, different from the one built into macOS?
Perhaps unrelated, but your description sounds somewhat similar to an issue that was reported here; however, we have already fixed it with 2025.3.1. Perhaps updating would solve the issue for you too.
Anyway, I would like to know about the tool/method you’re using for screenshots.
Thanks again for reporting!
