Mouse Wheel Bug in FreeBSD/TrueOS guest

[Oclair]

Hi There,

Whats broken: When running FreeBSD as a guest on any host for some reason the mouse scroll wheel issues back and forward browser (web browser such as Firefox or Chromium) commands in FreeBSD and TrueOS.

Whats expected: The Mouse wheel should only scroll up and down when using a web browser

Whats happening: The mouse simultaneously issues backwards and forwards commands in addition to scrolling up and down when using a web browser.

Scope: This issue affects FreeBSD/TrueOS VirtualBox additions for FreeBSD guests 5.1.10 and earlier /usr/ports/emulators/virtualbox-ose-additions This issue has no effect on guests which do not use the FreeBSD OS type in Virtual Box host. There is no effect switching between ps3/usb tablet settings on the host config.

I posted briefly in the Virtual Box forums on this issue ​https://forums.virtualbox.org/viewtopic.php?f=4&t=80912&p=379748#p379748

And have had some nice folks in the TrueOS chatroom track down that this bug seems to be limited to Virtual Box's FreeBSD mouse driver.

Jeffrey Baitis @baitisj posted in the TrueOS chat the following: so here's the proof. That's running xev and showing the mouse events when I'm scrolling the mouse wheel up and down., I tried the same test in a linux host, and it worked fine. There's clearly some issue with the freebsd virtualbox input driver

Thank you for your assistance! Jason
