Hi and welcome to the forums
Does other Qt apps ( like any of the demos) run ok on that win 7 ? -
This desktop app has been developed with Visual Studio 2010 and QT 4.7.4 and run since 2012 onto W7 and then W10.
We decided to update development tools and ran onto W7 and W10.
A significant work has been achieved to move on Visual Studio 2019 and QT 5.13.2. Same app keeps on running on Windows 10 but fails on Windows 7 with this issue.
May we expect support from QT dev team on this ? -
Hello,
I am looking for a way to send you projet package. Could you point me out a link to upload a .zip file ? -
Hi,
If you need direct support from the Qt Teams, you'll have to contact the Qt Company. This forum is user oriented. One thing that you can do in between is check the bug report system to see if it's something known.
Another thing you can do is cut down your application to the minimum to see when it starts misbehaving.

Hi
You can use Google driver or dropbox or
similar and get a share link and paste link here.-on W7, a transparent windows on top of screen
Do you use openGl/QML or anything that would use directX or
similar ?
