Qt 5.2 Window transparent when enabling blending?
Seraph last edited by
I just updated to Qt 5.2 and the problem starts.
My application is using the openGL blending function to make objects transparent through alpha channnel.
I set up the blend function like this:
This worked since the big bang! But now: Wherever the blending is used, the window itself gets transparent!!! I can literally look through my window at these areas!
What did change? Do i have to use any QOpenGLFunction or QOpenGLContext stuff to make it work again?
I am using Windows 7 64bit on intel core i5 and ATI HD5650 Mobility Radeon with the latest beta drivers!
Again: 5.1.1 working... 5.2 wont!
I will downgrade to 5.1.1 for now.
Thanks in advance!
Since it might be a regression, I would recommend asking this question on the interest mailing list you'll find Qt's developer/maintainers there (this forum is more user oriented)
In between, you can also check the "bug report system":http://bugreports.qt-project.org to see whether it's a known issue. Maybe open a bug report with a minimal compilable example that shows the behavior change
