Segmentation fault in QSGOpaqueTextureMaterial::compare QT5.8
-
Hello,
We are encountering a segmentation fault with an application with 2 display; On CentOs 7.4 with QT 5.8. with intel graphics.
We can not find the origin of the QML code that provokes the problem.
Someone can help us ?
ThanksBack Trace :
