Download https://download.manjaro.org/xfce/22.0.5/manjaro-xfce-22.0.5-230316-linux61.iso +2. Start above command +3. Wait until the graphical desktop appears +4. Click inside the window and move the mouse + +-> Mouse cursor disappears or jumps around like crazy +Additional information: +If vmport=off is **not** passed, at some point during startup (before graphical login manager appears) the guest switches to use vmmouse from PS/2 mouse. There it also requests usage of absolute input coordinates (VMMOUSE_REQUEST_ABSOLUTE). This code path works normal. Therefore the culprit might be in the guest. + +Another way to reproduce the issue is to use -accel whpx under Windows host (no need to pass vmport=off there). It can be observed that the same guest doesn't attempt to switch to vmmouse there, just like passing vmport=off under Linux. + +The problem does not exist on Linux host when -accel tcg is used in which case the guest doesn't attempt to switch to vmmouse. |
