Hello Dusan, I'm forwarding to vbox-dev list,
I had an issue with virtualbox-qt since some version after 5.1.18 (5.1.18was the latest version I was using without that issue). The issue was that when virtual machine is set to fullscreen, minitoolbar was missing/hidden even that minitoolbar was set to be shown (no matter if on top or bottom of the screen). I've tried to google the issue and found few similar tickets/discussions on the net, but most of them has answers that it is caused by wrong version of qt and so on. So I thought it is maybe just my configuration and that it will be somehow solved after some library gets update or so (I'm using debian testing so I might have some old version of library left on the system). But then when after months I've found ticket https://www.virtualbox.org/ticket/17280 , I thought 'hey someone else has exactly the same issue, maybe it is not just my configuration'. So I've tried several versions of vbox from 5.2.2 back to 5.1.18 and I've found that the issue started to appear right in 5.1.20. So I've downloaded the (debian) sources of 5.1.18 and 5.1.20 and compared them to try to find the code which might be the cause of the issue. And so I've found that there was change in logic of function UIMiniToolBar::defaultWindowFlags(). In 5.1.18 was (for fullscreen) the default return value Qt::Tool | Qt::FramelessWindowHint with the only exception for X11WMType_Compiz for which was returned Qt::Window | Qt::FramelessWindowHint. But in 5.1.20 it was changed and the default return value was Qt::Window | Qt::FramelessWindowHint with the exception for X11WMType_GNOMEShell, X11WMType_Metacity and X11WMType_Mutter WMs for which the return value was Qt::Tool | Qt::FramelessWindowHint. So, for X11WMType_Compiz, X11WMType_GNOMEShell, X11WMType_Mutter and X11WMType_Metacity (which was new in 5.1.20) WMs the return value in 5.1.18 and in 5.1.20 was the same, but not for X11WMType_KWin and X11WMType_Xfwm4 (which is exactly what I'm using as I'm using xfce4). And so I've added X11WMType_Xfwm4 to the "switch" to return the same value as in 5.1.18 and compiled virtualbox-qt myself and the issue was gone (I've done it on 5.2.2 which was actual in testing at that time). The diff is: --- virtualbox-5.2.2-dfsg/src/VBox/Frontends/VirtualBox/src/widgets/UIMiniToolBar.cpp~ 2017-11-23 10:21:43.000000000 +0100 +++ virtualbox-5.2.2-dfsg/src/VBox/Frontends/VirtualBox/src/widgets/UIMiniToolBar.cpp 2017-12-18 03:42:49.719028477 +0100 @@ -413,6 +413,7 @@ case X11WMType_KWin: case X11WMType_Metacity: case X11WMType_Mutter: + case X11WMType_Xfwm4: return geometryType == GeometryType_Full ? Qt::Tool | Qt::FramelessWindowHint : Qt::Window | Qt::FramelessWindowHint; Can you please look at this issue and test it (vbox 5.2.2+, xfce4, VM with fullscreen and minitoolbar)? And if you can replicate the issue using debian package and if the diff will solve it, can you please consider to use the diff for fixing the issue for next versions of vbox?
