QTCreator + CDB (Windows 10 SDK) = bad performance

[m0wgli]

Hello! I have a problem.

I use QT Creator 4.1.0 and CDB 10.0.14321.1024 from SDK 10.0.14393.33 on Windows 10 Enterrprise.

I didn't find CDB in auto-detected debuggers and added it manually.
In QT Creator in Application output on start debugging I see:

Debugging starts
Qt: Untested Windows version 10.0 detected!

Initially perfomance was awfully bad. After I installed pdb packets from msdn it became better. But nevertheless now it sometimes takes up to 3 minutes to interrupt debugger.

Did someone suffer from such problem?

I remember experiencing performance issues on QtCreator 3.5.1 when I had expressions.
Have you tried clearing your debugger expressions ? No idea if it's related to your problem but worth checking!
