Created attachment 116122 [details] screenshot of the problem - start LabPlot 2.6 - click in the toolbar on the button "Properties Explorer" to suppress its view - now click the button again to make the explorer visible again result: there is only a white and empty field shown instead of the explorer
This is most probably caused by the animation we added for the dock widgets. We'll switch it off since it causing some other problems, too.
This problem is still in 2.6.0RC2. I found a workaround: Just click in the project explorer and the properties explorer becomes visible immediately. So it seems to be a simple signal problem for the Qt widget for the toolbar button. I mean the bug does not appear for the project explorer toolbar button. > This is most probably caused by the animation we added for the dock widgets. I don't think this is the problem but nevertheless I don't see why e.g. hiding a dock widget must be animated. Therefore please remove this if it could make problems.

Deactivate the animation of the toggling of dock widgets for a moment since it produces unwanted remnants on the MDI area.
