[Qt-interest] TimerEvent processing issues with Qt4.6 when no other event occurs

[Frederic Tingaud]

Hi,

Since we migrated from Qt 4.5.2 to Qt 4.6.2, we experienced a very
strange bug with TimerEvent processing under Windows (any version from
XP 32 to Win7 64, but not under Linux). Sometime, if we let the
application run without interacting for a few time, the TimerEvent in
our main window stop being called. If any event happens, like a mouse
move, a key press or anything, everything goes back to normal and all
late timers are processed. We couldn't reproduce the bug in a minimum
test case and when we try to add QDebugs, it seems to reduce the issue
occurrence.
Does any of you ever experienced this or have any idea about how to find
out what's happening ?

Regards,
