@erqunet this looks like vvvv cannot initialize drawing. what operating system/graphics card/driver is this? can you try on another device?

[erqunet]

@joreg thanks for answer. yes it looks like this. i tried 2 time on diverent operating systems but the same machine. first on win7. second at upgraded win10. both times i had the same problem. the grafikcard is NVIDIA GeForce 310M. i wandering when i had win7 the grafikcard had status “working with no problems” in device manager. no on win10 the operating system can not initialize a driver for this device. it works with Intel HD Grafics. It seems the grafikcard is to fucking old.

ok that explains. in that case i can only recommend using a newer card or finding a newer driver for it.

ok thanks. i´ll try
