Hello,
i have compiled my project on a machine running Debian Stretch and out of a sudden get many of these errors:
QXcbConnection: XCB error: 8 (BadMatch), sequence: 2409, resource id: 117440720, major code: 130 (Unknown), minor code: 3 QXcbConnection: XCB error: 8 (BadMatch), sequence: 2429, resource id: 117440720, major code: 130 (Unknown), minor code: 3 QXcbConnection: XCB error: 8 (BadMatch), sequence: 2432, resource id: 117440720, major code: 130 (Unknown), minor code: 3What is this? (it doesn't seem to cause any problems, but still it can't be good to ignore it)
On Windows 7 as well as on another machine running Kubuntu they don't appear.

Hi,

-
Hi,

-
What desktop environment are you using ?
What window manager ?
-
Hi,
the desktop environment is KDE with kwin as window manager.

kwin version is 4:5.8.6-1
-
Are you using the distribution provided Qt ?
-
@SGaist yes its the distribution Qt version.
i'm not sure if it has something to do with this, but i noticed, that i get some compiler warning about VTK:
VTK version is VTK-8.1.0warning: 'QVTKWidget::QVTKWidget(QWidget*, Qt::WindowFlags)' is deprecated [-Wdeprecated-declarations]or maybe you can tell me what the error means because i have absolutely no idea where to search for
-
That's not an error, it's just a warning that you are using a method that is considered deprecated and you should consider updating your code.
