Hello,

I have a Windows 7 guest system on Kubuntu 18.04 host. VirtualBox is 5.2.10_Ubuntu r121806. In last versions of VirtualBox the Win7 guest has a keyboard lag: when I press and hold arrow keys, it is moving slow and stops moving, and after resuming it sometimes behaves as if Shift is pressed, i.e. starts marking everything. Here is a video: https://youtu.be/RcfPGgEzv2g. Is there something with my system, or it's a VirtualBox issue?

Thanks.

That isn't VirtualBox, that is a fork. Please go to the Ubuntu forums for support of their fork. If you want support here then you need to purge the fork and install the correct version from the download page of this site.

I've installed it, and the problem has gone. Thank you!
