Error 6 transferring internal Bitmap using BitBlt

[VideoTrack]

I have an application using a TeeChart

Occasionally, I get an error:

"Error 6 transferring internal Bitmap using BitBlt"

which should not occur.

There is nothing complicated about the calls, and it runs fine on many systems, but has issues I think on a Windows 7 system after upgrading to the latest version built on Win 10 - although not sure. This never happened in the past. The code is about 8 years old with no problems and no changes to the Chart code, but now the error occurs.

Attached is Zip file of debug.

it seems to occur in 'VCLTee.TeCanvas.pas'

Please advise what I can do.

Thanks
Trevor

Hello,

Can you please attach the project again?

Hello
The project is quite complex and requires many other inputs.

But I attached (I hope) the zip file of the error trace log.

Hello,

Thanks for the log, but we'd require something more to be able to reproduce the problem here.
I understand simplifying a big project to the minimum or arranging a new one with the minimum code to reproduce a problem sometimes isn't so easy. Sometimes the problem can be reproduced just loading a tee file.
Could you please try to export your chart to a .tee file and send it to us (in a zip)? Then, we'll try to import it and see if we can reproduce the problem.

Thanks in advance.
