Zoom shortcut (control + spacebar) 'stuck' in the list of blending mode

I just wanted to report this, as I don’t know if it’s a bug or if it’s related to Linux Mint (Zara version), since this didn’t happen on Windows.

Krita 5.2.14 (this has also happened with the previous version)

Here’s the thing:
I have the brush tool selected, so I go to the layer manager and change the blending mode of one of the layers; then I go back to the image and try to zoom using the shortcut control + spacebar; that’s where the ‘problem’ starts because, when trying to use this shortcut, the list of blending modes keeps opening and closing as if the cursor and the action/command were still there.

To be able to use this shortcut, I need to click with the brush on the image I’m working on (or use the shortcut to turn the brush into an eyedropper, because that way I don’t paint the image). After that, I can use the shortcut to zoom without the list of blending modes opening and closing.

This is something I do a lot and it didn’t happen on Windows.

Thanks,
