This is an old revision of the document!
This superuser.com post outlines the issue and a fix. But here it is again in case that link breaks:
When linux is a guest, in certain applications scroll wheel events stop being received by certain applications when the mouse pointer is moving. This happens in vmware
and virtualbox`` and in multiple distros. For me it was most noticeable with Chromium, and frankly, a deal breaker on using linux desktop virtual machines. It was the main issue that drove me to dual boot. Anyhow, I don't claim to know exactly what this does but it does seem to work. These instructions worked with Ubuntu 18.10 and will need appropriate modification (e.g. package managers and package names) for other distros.
