Re: [Interest] Massive flickering while resizing Qt Quick application while resizing the window (Windows only)

[Rui Oliveira]

This is a very well known bug:

https://bugreports.qt.io/browse/QTBUG-93084

+ other 50 clones...

Hi,

I have never realised until today that there is a massive
flickering when resizing a Qt Quick application window.

This happens even with the minimal Qt Quick application template.
When doing the resize on a complex application it looks like rubbish.

There is a massive amount of flickering bug reports open for this
topic.

I’m currently using Qt 5.15.9 but it seems this is still an issue
on Qt 6.X

Is this a well know issue?

How can we deploy professional applications with such behaviour?

Thanks!

Regards,

Nuno

Hi,

YMMV but I have generally seen the resize performance get better after
forcing QtQuick to use ANGLE for rendering. You could try and see if that
works for you.
