When using a grindstone in the game it gets even worse, and breaks the cursor even more, and after that consistenly isn't centered when using for example an enchantment table.

This is still reproducible and it happens in Counter-Strike 2's buy menu too.

Hi, someone in the KDE Discussion website and I both have the same problem and is quite annoying. https://discuss.kde.org/t/mouse-can-move-in-games-when-it-shouldnt-be-able-to-and-it-isnt-visible/19565.

Are there any updates regarding this problem? It is still reproducible in minecraft on my system (fedora 41 KDE 6.2.5 wayland)

The other person with this issue has a nice video displaying the issue. https://youtu.be/xQWZdzZULCM.

Thanks for everyone's time 🙂
