Hello,
I just got a new laptop and tried to install Manjaro on it with KDE. I have an Intel Alder Lake-UP3 GT2 [Iris Xe Graphics] and the screen is behaving in a very weird way. There is a band at the top of the screen that works perfectly. It is about the size of a third of a pointer and here the mouse works perfectly. Everything is smooth (I can see the mouse moving normally). The rest of the screen though lags completely. The pointer makes jumps and is not smooth at all. I have no idea what is going on. If someone had an idea…
