Currently there are no Debug configuration CI clients active. This can potentially lead to missed errors because of uncatched failed assertions or runtime debug checks of containers using MSVC. I suggest we create at least some nightlies for this or change the continuous to debug since this would also increase build performance.
I agree that we should have debug clients but not as Continuous, as at least on Windows Clients Debug builds are not faster but at least quite some time slower because of very long execution of tests with lots of image pixel access. Nightly clients in debug mode should make sure not to execute package tests as long as we only support release mode installers.
