I am having a recurring problem regarding the cursor when I have Parallels open. Very often, I get a flickering cursor within the virtual machine and the only remedy is to restart the VM and sometimes my Mac entirely. I have run into problems where the cursor flickers within Mac OS X in addition to within the VM. Most recently, my cursor was flickering in both and when I would right click, the mouse would write the number 1 over and over, in addition to the keyboard writing number 1 as well. Immediately after shutting down the VM, there was no problem. Within the last two months I have reinstalled Parallels tools when the flickering cursor became absolutely unbearable immediately upon start up. I am running Mac OS X El Capitan w/ Parallels Version 10.3.0 (29227)
Hi DerrickR1, Please shut Down virtual machine and open Virtual Machine configuration, go to Hardware > Boot Order > and paste in Boot Flags box: video.hw_pointer=0 In Windows guests there still will be situations where cursor becomes invisible. Also there may be occasional screen flickering. In summary, the above solution will work fine when using virtual machine for simple tasks such as document processing, but heavier use (like games or 3D software) may make system unstable.
Hi DerrickR1, Please shut Down virtual machine and open Virtual Machine configuration, go to Hardware > Boot Order > and paste in Boot Flags box: devices.usb.mouse=0 and let us know how it works.
