It's still the same with the changes to surface_interface.cpp. But you were totally right about the input devices. I currently use a Logitech G502 and I can't reproduce the problem with other mouses (even another Logitech model). With the G502, the problem appears only in Adaptive mode for the acceleration profile. It's ok on the Flat mode. I also tried with different DPI on the different mouses (configurable with a button on the logitech ones), it's the same behavior. -- You are receiving this mail because: You are watching all bug changes.
