Ok, so this I have been able to reproduce and will fix shortly.
Thanks for you reply. I can’t find any downscaling options in my source settings. Can you give me a hint?
The setting is a bit hidden, from the live single view on the right part you can open the plugins property. Under recording plugin, there is a downscale setting. This was probably herited by previous version.
I’m releasing now 1.1.5 which should anyway disable totally the downscaling.
Closing the topic.
Official 1.1.5 is about to be released and should fix the recent issues reported with 1.1.0 RC2 such as recording fails on some video sources.
