VBox: 5.0.26r108824
Guest: Linux Mint 17.3
GA version: 5.0.26r108824
Recently updated the GA to 5.0.26r108824. Now I'm running into rendering problems with Chrome and Opera, but not Firefox or other desktop apps, like LibreOffice. See images:
Opera:

What's even more funny is it's grabbing bits of screen from my Host OS, where I'm typing this into...
Any thoughts?
Looks like a vbox 5.0.26 rendering error...
Other applications, like LibreOffice 5 Writer & Firefox, seem to be rendering fine.
...and when I go back to the OS (close out of Opera, for instance), the main menu is hosed until I reboot:

When I turn 3D acceleration "off" the guest goes into software rendering mode, and the browsers display fine.
Any idea how to fix?
Thanks!
