Cursor gradually disappears and then reappears at once when moving mouse horizontally. This happends on vertical line exactly in the center of the screen. It creates impression there are 2 tiles on the screen, (left and right). When mouse moves to the right edge of the left tile it gradually "hides" under the one on the right side, when when the cursor is whole on the right tile it "pop ups" again at once.
This happends even on external monitor, where resolution is different, it still dissapears exactly in the center of the screen.
This does not happends when both monitors are used as outputs (orientation does not matter, they can be left, right, above, bellow of each other or even overlap). I did not find any horizontal line where the cursor "hides".
Also in some positions along the central line sometimes some artifacts appears, when the mouse is partialy hidden. They change when the mouse moves in any direction. But those are not always reproducible and in fact are rare.
I actually does not have an idea where the bug actually is (can be anywhere along the pipeline including kernel).
This is on Lenovo A485 notebook with Arch linux.
