Does this still happen if you disable the DisplayFusion Multi-Monitor Tasbkar feature?

That shouldn't really make a difference. We do have some big improvements coming to the startup performance for the next beta, so hopefully that will sort out the issues on your machine. We'll follow-up as soon as it's available.

Thanks!

Wow, that's an interesting one! I haven't run into that here but we'll see if we can reproduce it with the latest drivers. If we can, we'll look into it further.

Thanks!

We've got a test build of DisplayFusion 11 Beta 1 that we're not quite ready to release to everyone through the auto-updater, but thought you might like to try out as it may resolve the issue you reported. This beta has some very big behind the scenes changes that will improve performance, speed up startup times, re-organizes the main settings window, and adds real time settings changes. We've done a lot of internal testing, but be prepared for a few bugs. We'll collect feedback over the holidays and review it all in January.

Please take a backup of your settings (Settings > Options > Export) before updating and store them outside of the default folder. If you need to roll back to 10.1.2, you can download it at https://www.displayfusion.com/Download/ and install it over top of the beta.

If you'd like to give it a try, you can download it here: https://www.binaryfortress.com/Data/Download/?Package=displayfusion&v11-test=1

I can't seem to reproduce the same issue with the 546.33 drivers here, but maybe it's video card specific. Which video card do you have?

Just a quick update on this, we've been trying to reproduce the issue without success. Are you all still running into this with the latest version of the NVIDIA drivers?
