Overlay window is blank (white)

[hdradio]

Last night I formatted my hard disk and reinstalled windows 10. I let windows to install all my drivers. All went fine.
I then installed PFOA and run it.
I waited until the next overlay and... it showed correctly !!!
I let the pc running OnAir and today I was going to post that everything is ok...
BUT: This morning I again waited for the next overlay. Unfortunately it was blank again.

I PM you the config folder.

Hi Dimitris,

the guys at DevExpress are still unable to reproduce the issue, as well as i am.
However, they provided a new version of their UI lib with several optimizations and smaller bug fixes; so maybe this one is fixed as well.
A new v4.0.1.50 update is therefore available...

I updated to v4.0.1.50 hoping that it fixes the issue.
PFOA started and displayed the overlay window normally.
An hour later that window became blank again.

What I don't understand is that's the only window in all OS apps that is blank.

Yes that is indeed strange, as it is painted like any other window. It is also really bad, that you are the only one seeing this issue. Even the UI lib vendor was trying hard to reproduce it with my source code, but unfortunately wasn't. It just makes it so hard to find anything, if no one can reproduce it.
So we have to continue our 'blind' search...

In "Error.log" I see a lot of errors like this:

Hi Bernd
I report that the problem is fixed with latest update v4.0.1.51
Running almost a day now and overlay window shows ok.

I am glad it wasn't my system's problem but PFOA's. Because I had tried all the solutions I could imagine including 2 formats and reinstalls. Pfff. That 's a relief for me.

[radio42]

For me too!, I am glad the UI lib vendor finally found it!
Thanks for letting me know...
