For images of my bug : https://3dsystems.teamplatform.com/pages/94919?t=da2ssnhu4f0vI use : Qt5.0.2 and compiler mingw47_32
I work on windows XPThe problem concern only QFrame, QSpinBox, QComboBox but doesn't affect QPushButton, QProgressBar, QToolBar and others of my Widget. Globaly all of my widget that i refresh cyclically.
It seems to be a problem of refresh or something like that but don't know exactly what ! Is there a memory or a stack that manage that can be full? Or a signal/slot that need to be disconned?
Thanks for for help SGaist

IIRC Xp is not anymore supported by Qt.

IIRC = "If I recall correctly"
AFAIK XP is still supported, however the pre-built Qt Creator might not run on it
