Dmitry Kazakov <dimul...@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|REPORTED |RESOLVED --- Comment #8 from Dmitry Kazakov <dimul...@gmail.com> --- Okay, the but should now be fixed: Windows: works fine Linux: works better, but still lags a lot On Linux it is not possible to fix the problem completely without adding a lot of hacks into Qt's QXCBConnection code. The problem is that XCB just drops some XCB_MOTION events for the mouse's scroll wheel, when the tablet is present and sends updates using DEVICE_CHANGED events (XCB_INPUT_REASON_SLAVE_SWITCH). And it is very difficult to generate QWheelEvent from a device-changed event (it lacks windows handle, screen position and modifiers). -- You are receiving this mail because: You are watching all bug changes.
