This is a known problem. We'll try to fix it for the upcoming release 2.5.

P.S.: a lot of icons in the toolbar and a lot of entries in the main menu are missing in your screenshot. It looks like you didn't do 'make install' yet. You need to do it once so the different application artifacts like the definition of the main window, preview images for themes, etc. are installed correctly and can be found by LabPlot.

confirmed on OpenSUSE 42.3 if using File->Open before. But not when started from command line ("labplot 2 test_labplot.lml").
Comment 4 Stefan Gerlach 2018-02-11 17:00:31 UTC 
It seems to be a bug of older Qt versions. What Linux distribution and which Qt version do you use?
Comment 5 Matthew Trescott 2018-02-12 03:31:19 UTC 
Arch Linux, Qt 5.10.x
Comment 6 Stefan Gerlach 2018-02-15 20:43:16 UTC 
I could reproduce the problem with Qt 5.10 on Arch Linux. We have to think about a solution.
Comment 7 Christoph Feck 2018-02-16 00:05:47 UTC 
Is this a QMdiSubWindow? If yes, it is the Breeze QStyle that adds the shadows, and it is possible that it is a bug there.

Yes, this is a QMdiSubWindow.
Comment 9 Stefan Gerlach 2018-11-11 08:24:27 UTC 
The problem is still present on Arch with Qt 5.11.2 but doesn't seem to happen on Windows 10 (Qt 5.11.2).

The problem is still reproducible with the current versions of Qt and KF5 on an up-to-date openSuse LEAP 15. Christoph, what would be the best place to report and to fix this problem?
