There is a new bug report that I think is the reason for this problem here: Bug 528076: Impossible for mouse to reach right/bottom screen edge at 200% scale and above On a 4K monitor at 200% scaling, the right edge of the screen has logical pixel coordinate 1979.5 but the mouse pointer is not allowed to use that coordinate, it gets clamped down to 1979.0. When using a mouse pointer speed of -0.50, the mouse data from libinput is +0.5 pixel steps instead of +1 pixel steps, so at 1979.0 and moving the mouse slow enough that it's not jumping over pixels, it gets stuck because it can't move into pixel 1979.5. I have my mouse set up at 1600 dpi and 1000 Hz polling rate. Moving the mouse slow enough to run into this problem here means moving 1600 pixels in a second which is about 25 cm of distance in a second on my 27 inch 4K monitor. -- You are receiving this mail because: You are watching all bug changes.
