Hi André Sorry for bailing out last summer. I thought id give it another shot this weekend. I updated the svn version. With the vanilla svn versioen the problem still stays the same. cal@helvetia:~/no-backup/archive/xflr5/svn/xflr5-code/xflr5$ svn info Path: .

Hi André It still crashes, however without the message about the recursive repaint. Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Hi André I tested it on an other, older Kubuntu 18.04 as, from your description, it seems to a race condition between two threads. On this older an slower box, it does not happen, only on my relatively new Core i7-8550U Notebook. I will glady test a new relese or a svn version. Thanks, Michael

Hi André Thanks for your reply. I don't know qtcreator but I think I managed to build a debug release. However either is really in the QT libs (only) or I did not get everything right as my trace ssems to schon more or less QT only stack trace.

Hi All xflr5 segfaults in Wing and Plane design mode everytime I chose to dosplay the Surface Velocity or Stream in the Results box. cal@helvetia:~/archive/xflr5/xflr5$ LD_LIBRARY_PATH=./XFoil-lib/:./xflr5-engine ./xflr5-gui/xflr5 QWidget::repaint: Recursive repaint detected Segmentation fault (core dumped) I tested a few of the recent versions got the same behaviour with all of them.
