Display - Plot Spectrum - Background and Refresh

This is an issue that just occurred where the background of the Plot Spectrum - Frequency Analysis window has gone transparent and what is behind the window shows through. Additionally, any changes to Algorithm, Size, Function, Axis etc. occurs, but the window is not refreshed and both the old and new content pollute the Frequency Analysis window.

System has worked fine in the past. It is a Win7 Pro 32bit. I had recently loaded two other Spectrum Analysis applications, I removed them, and clean installed Audacity b1.3.13 (the problem was first noticed with b1.3.12) thinking they used a common component. It made no change. The same three programs are running on a 64bit W7 system with no issues.

It appears the FA window is being called from within the executable, and not as a plug in. I have reviewed all the Preferences and cannot see anything that might cause this.

Anybody got any ideas on how to proceed with the troubleshooting ?

It's a known bug and already listed in the 1.3.13 Release Notes. However only a small minority of users are affected by it and hitherto it had only been reported on Windows XP and 2000.

I would assume it to be a conflict between wxWidgets and one or two specific video card drivers. So the next step would be to identify the display adapter and try different driver sets for the adapter.

Thanks Gale, apologies for not picking that up in the Release Notes.

I was using Remote Desktop Connection when I noticed this, but when I go to the local machine it does not display the phenomena so for me it is not an issue anymore. I now know how to work around it.

Thanks, I tried Remote Desktop between two Windows 7 machines but there was no Plot Spectrum issue.

If you run Audacity natively on the computer you were using as client, does it have the same Plot Spectrum issue?
