Dual screen window size problem

[Mitchell]

Certain programs don't seem to co-operate well with a dual monitor setup. If it is of any importance, my setup is a laptop with a TV plugged in via HDMI. So far I've found that VLC media player and Oracle Virtualbox won't play nicely with two monitors. When both monitors are in use, virtualbox crashes before it can open, and vlc tends to freeze the entire system, requiring a hard reboot. If I run these programs while only one monitor is being used and plug in the second one, they'll start misbehaving if moved to the other monitor. virtualbox and vlc will both become way too huge to be usable.

Thank you for your bug report, the issue seems with vlc and similar to what is discussed on https://forum.videolan.org/viewtopic.php?t=144265

do you use some scaling factor on those screens?
