maintainer-feedback:
Bug 245701: emulators/virtualbox-ose: severe graphics distortion
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245701



--- Description ---
Scenario:
- running virtualbox on FreeBSD 12.1-RELEASE-p2 amd64 host
- nvidia quadro 1000m graphics card
- latest ports
- virtualbox-ose has been updated to ports r531736 (switch to clang for
compiling)

Result:
- The Virtualbox main window has severe graphics artifacts - it is not
displayed correctly (see attachment - the right part of the window is entirely
unrelated to the rest; there can also be scrolling artifacts)

Scenario (continued):
- Starting a client running Windows 10 or Linux

Result (continued):
- The Virtualbox client windows have severe graphics artifacts - they are not
displayed correctly
- Updates to the window contents by the respective clients are
distorted/partial/misplaced
