Stylus input broken after updating Ubuntu to 26.04.1

Type of device: 2-in-1 laptop
Brand and version of the device: HP Spectre x360
System : Linux Ubuntu 26.04.1

Description of the issue (you can include screenshots):

Soo I foolishly updated my OS to the newest Ubuntu 26.04.1 yesterday, and since then Krita (tested on 5.3.3 as well as 6.0.4-prealpha-2679852fa0, I’m running the .AppImage in the terminal without any options) does not recognize the stylus input anymore.

The stylus works everywhere else when using the laptop, as well as in the settings

In Krita I cannot draw, nor use the menus or toolbars using the stylus, a second cursor appears but it is useless.

The log says

WARNING: the destination object of KisSynchronizedConnection has been destroyed during postponed delivery
The imageRectInWidgetPixels topLeft() does not match the documentOffsetF!
imageRectInWidgetPixels: QRectF(-0.1,-0.1 0x0)

but I cannot say if that is relevant to my issue.

It’s probably the xwayland bug: Touchscreen stylus not working on Gnome 50

Downgrading xwayland worked.
The version 24.1.9 was not available in, so instead I had to download the .deb from launchpad.net as this comment from another thread said:

Ubuntu 26.04 LTS & Krita AppImage not compatable?

It does sound exactly like the problem I had. Though that was with wacom. You mention setting to update Xwayland, which I don’t know about, but downloading the package manually and installing it works for me (requires computer restart to work though) you will have to do this each time you update ubuntu. Thankfully I can see an update is in the works for Xwayland.
