This may be a Windows 11 issue. When running VarAC 6.0.8 on my machine with a Radeon 6600 graphics card, I get screen flickering. The screen will go black for a few seconds. When it comes back on, the VarAC windows is pure black. If I click the title bar and move it around, everything is then displayed correctly.

Irad, I think the problem actually lies with the VARA modem. I had the modem running with nothing else running just now, and I still got the issue.
Well - I have done a lot of reading. Seems like a driver issue with windows that is somehow triggered by some .NET applications. Not much I can do frankly as I cant simulate... but if you happen to solve it, please share with us so I can spread the word.
73s!

I see all your screens flicker. not just VarAC.
You mean that VarAC cause all your screens to flicker ? or when all your screen flickers VarAC is the only application that does not recover ?
I tested the VARA modem by running it alone and the issue did not occur.
I also just RDP'd int the machine running VaraC and still got the flicker, so it appears the issue isn't linked to the graphics card.
I will need to see a video of it to better understand it as I have no way to simualte this bug as I dont have your setup.
I have verified this doesn't happen with VarAC closed.
