MainWindow goes Blank

[jamat13]

Intermittently
Sometimes overnight (Ie no interaction for hours)
Sometimes on action <click>

Normal is 50% memory used (50% == 4G), no swap (32G)
I'm running vmstat to see if mem usage changes

Background processes (video recording with gstreamer - heavily threaded) launched with startDetached continue running

app is qmake c++ code with Qt6
gstreamer renders in a QWidget.

Any ideas on how i could track down. There is NO coredump.

Hi,

Which OS are you on ?
If macOS, you could start by sampling your application to see if there's something unusual going on.
