#2970 new defect

Redrawing of DataGrid in Data Preprocessing is horribly slow

Reported by: gkronber Owned by:
Priority: medium Milestone: HeuristicLab 3.3.17
Component: DataPreprocessing.Views Version:
Keywords: Cc:


When I run HL in a maximized window on my notebook and I select the data grid then I can watch while each cell is redrawing after each other. It takes more then 10 secs to redraw the visible part of the data grid.

The process is much faster if the window is in the background.

Interestingly, while HL is redrawing the process is almost idle (1% CPU time) but the GUI is unresponsive.
