I noticed while Dragging Application Windows there is a delay in the mouse that creates a duplicate mouse Icon has anyone else experienced this? I have not had this problem with Windows 7, or the Previous version of Virtual Box. If you drag an application Icon you do not see the same issue.
running on Linux Host. Ubuntu 18.04

We're going to need a complete VBox.log, from a complete VM run:

• Gathering the necessary information:
  1. Start the VM from cold-boot (not from a paused or saved state).
  2. Observe the error, i.e. drag a couple of windows around and see the double cursor.
  3. Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Here is the Log.

00:00:01.068609 GUI: 2D video acceleration is disabled

And so is the 3D acceleration. Shutdown the VM and enable them in the VM settings » Display. You'll also notice that the max VRAM will jump from 128 to 256 MB after that; max the VRAM as well. Then re-install the Guest Additions (GAs) in the guest. Oh, and always remember to eject the GAs CD after you're done with the installation...

You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors (cores), not logical ones (threads). See "CPU Cores versus threads" and "Why is it a bad idea to allocate as many VCPUs as there are physical CPUs?".

Your host's Intel i7-6700HQ CPU has 4 cores. I would assign 2 to my VM, definitely not more than 3. BTW, if you visit Intel's information page, make sure you click on the "?" next to the Cores and the Threads.

00:00:05.913403 VMMDev: Guest Log: VBoxGuest: Windows version 10.0, build 17134

That's the newly released latest Win10 update. Even the latest of the latest of the VirtualBox test builds is older than that (last update 2018-04-27). So, if there are any kinks, after you address the issues above, let us know...

ahh Windows upgraded didn't notice that.

I have done all the steps listed still see the Issue attached are the logs.

And some more, no?

VirtualBox VM 5.2.10_Ubuntu r121806 linux.amd64 (Apr 26 2018 08:49:04) release log

Why did you install the Ubuntu fork over the official version? An itch? You can either ask in their forums for help, or completely remove/uninstall/delete/purge their version and install the official version from the Downloads section of VirtualBox.

oh Sorry I was playing with the one from the shop to see if it acts differently I removed it and re-installed the .deb from this site. Here are the logs.

hmm when I disable mouse Integration the issue goes away but its really difficult to control the mouse.

Problem still occurs on new version of Virtualbox attached is the logs.

Can you try with something simpler, like one monitor?

Intel isn't known for its high quality graphics drivers, we've seen a variety of issues in the past

00:00:00.832954 MonitorCount <integer> = 0x0000000000000002 (2)

Could you lower it to your virtual monitors to 1?

00:00:01.641570 [/USB/HidMouse/] (level 2)

That line is missing from your config. Do you have your Pointing Device set a PS/2 mouse?

00:00:47.995817 OpenGL Warning: blit from texture to texture not implemented
00:00:48.722869 OpenGL Warning: blit from texture to texture not implemented
...

And then you get more than plenty of these messages, which again point to poorly written drivers.

That's all I have. Just try to keep it as simple as possible at the beginning.

Here is the Updated Log. with Single Monitor

You log looks fine. If you're still having issues, here are some tips:

• Disable 3D acceleration.
• Try to update your GPU drivers.
• Lower the resolution of your guest.
• Take a look at ticket #12746.
• Read the following: 3D support for X11 guests.
