Titlebar + Application Borders are not painted in Windowblinds

[RealRaven]

I am running vbox under Windows 7 Professional with Windowblinds installed. No matter what theme I use or even if I excluded skinning for virtualbox, it is probably trying to paint its titlebar itself and fails very badly at it. The titlebar shows: the application icon at top left; a black title on a completely transparent background which is blurred. There is no background color to the titlebar, the minimize, restore, maximize and close buttons are invisible (so I have to guess about their location if I want to click any of them). Also, no borders are painted around the window, which makes resizing difficult as well.

In Windowblinds, it is possible to completely exclude applications from skinning, (which usually makes them show in Windows95 style) but this does not make not any difference. I am running a lot of different software & development environments (I also code for Mozilla, Fx & Thunderbird Addons) but I haven't seen this particular problem with any other software.

Have you tried to run other Qt-based GUI software, to check if the problem is related to Qt and WindowBlinds, and not to VirtualBox itself?

Replying to mhanor:

I don't know, what is Qt? I have just upgraded to 4.3.6 and the problem is still persistent. I am running a lot of software on this PC, but I have never seen this issue with any other software so far.

I think this regression was introduced in the previous version (4.3.4). Before it I had version 4.2.6 installed where it worked fine. btw is there any way to be notified via email if the ticket is answered?

just to test your theory I have installed the qt based windows version of this editor:

which I believe was updated on Nov19th and it does not have this issue.

Try a Qt4 based application. About the e-mail notification, search your spam folder.

Just a heads up, I just installed v 4.3.10 and the problem is still ongoing. interestingly it also affects the installer: completely transparent titlebars with no window controls (min / max / close).

Also, I tried "disable visual themes" but this doesn't make any difference.

Please reopen if still relevant with a recent VirtualBox release.
