Hey, 
From what I understand, you mapped the Shift key to a button of your tablet with OpenTabletDriver? 
I guess it is a bug for here then: https://github.com/OpenTabletDriver/OpenTabletDriver/issues 

Also possible: Krita is not yet officially supporting Wayland.  So, your version runs on a Xwayland windows as a workaround and a bug comes from this layer. 

In both case, it will require a bit of research to find where the problem can come from. I hope you can run another distro/D.E. with a tablet setting and test if this behavior is still here. This way you can blame OpenTabletDriver, Nobara Package, or Hyprland settings for Wayland and XWayland windows. 

Meanwhile, it doesn't look like a Krita bug; but I might be wrong. I put the report into a NEEDSINFO/WAITINGFORINFO if you can provide the test mentioned with another D.E. and way to setup the tablet. Good luck.

I press shift on my keyboard and drag with my pen on the tablet, it's the default binding, I have no bindings other than right click and mouse wheel button on the pens 2 tumb buttons, using the KDE plasma tablet support on Plasma Wayland works fine as far as I remember.

Thank you for your reply. 
OpenTabletDriver doesn't input the Shift, because you use the keyboard and everything works fine on KDE Plasma Wayland. This really put last to blame on the list:
- Nobara Krita package -> Please test with the official appimage. 
- Sway/Hyprland way to handle libinput for apps running on Xwayland windows (if you can still reproduce with the latest appimage, report to them).

I am on flatpak, I will try the appimmage... Strange tho, doing the resize using the mouse works as intended 🤔

So it does happen in appimmage too, gonna do a bug report on the hyprland side.
Thanks
