Windows Server 2019 / Two Screens / Flickering mouse pointer

Post by OliPoll »

Hi,

I am using 7.0.4 on Win 10 running a Win Server 2019 in the VM with the newest Guest Additions installed. 3D acceleration disabled.

The host notebook has 16 GB RAM, two screens (monitors) attached.

When I activate in the settings that 2 screens should be used in the VM, I get a very annoying flickering of the mouse pointer, whenever Windows show the "waiting mouse pointer", e.g. the blue circle.

Note: All works fine when only one screen is used in the VM.

Any hint is appreciated.

Thx
Oli

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Replace or remove the mismatched extension pack.
00:00:07.293386 Oracle VM VirtualBox Extension Pack (Version: 6.1.40 r154048; VRDE Module: VBoxVRDP; Crypto Module: unusable because of 'VBoxExtPackVMRegister returned VERR_VERSION_MISMATCH, pReg=0000000000000000 ErrInfo='Helper version mismatch - expected 0x30000 got 0x50000'')
Reduce core count to 2, and RAM to 6192MB.
00:00:07.579543 NumCPUs <integer> = 0x0000000000000004 (4)
00:00:07.579545 RamSize <integer> = 0x000000027a000000 (10 636 754 944, 9.9 GiB)
Let's see where that gets us.

Hi,

thanks. I 'm pretty sure that the guest additions were the newest version. Nonetheless, I reinstalled them to be 100% sure. Also reduced the CPUs to 2 and the RAM to 6 GB.

Unfortunately, still the same effect.

Cheers
Oli

Guest Additions != Extension Pack. Please take a look at this again.

Then provide a new log so we can see what's happeneing.
