Description Per-Arne 2019-03-20 07:57:11 UTC

SUMMARY
When doing "drag selections" (Left click and drag) on the desktop is done, the mouse loses sometimes while doing so.

If its relevant, the mouse used is Logitech G903.
I have not been able to track down what is causing this behavior. Tried to close all running applications one by one, without luck.
The bug occured after updating the arch system.

STEPS TO REPRODUCE
1. Hold left mouse button
2. Drag mouse around the desktop, or in any application
3. The mouse should now lose focus arbitrarily

When it only happens when you're dragging a box on the desktop like this? Not ever in Dolphin or any other app? On first glance, it looks like a hardware problem with the mouse. Do you happen to have another mouse you can plug in and try?

Hi,

This was indeed a hardware bug. Should have closed this off "ages" ago, Sorry!
