that would wear on me, too - but I don’t recall ever having that issue on my Cubase on Win10 setup.
Does it also happen if you start with an empty project with only a single track and no plugins loaded?
Do you maybe have a screen capture you could post?
The issue does occur in a totally blank project with only one audio track and no plugins. I should say the channel window closes as expected sometimes. It’s every 3rd time or so I have to click the elsewhere in the window before the “X” works to close it.
If I had to guess, it’s a problem with window scaling. I have a 4k TV and a 1080P monitor. I run the mixing window on the 1080P and project window on the 4k. When I do juggle plugins between the monitors, scaling is definitely gitchy. I do not run into this problem in Ableton, so Cubase must handle window scaling uniquely.
I’m going to use it a fair amount today, so will update with any more consistencies I notice as well as a screenshot.
NOTE: I’m running an Nvidia 2xxx have tried a handful of graphics drivers (via Windows Update and last 3 revisions via Nvidia.
I’m running a relatively similar setup to yours: 4k TV as first monitor and a 1440p monitor as the second one. And both are driven by an Nvidia 2060. However, both screens are running at native resolution, so that might be a difference.
As a work-around, have you tried making a key command (beware there are two different one’s called “Edit Channel Settings” - it seems to work for me with the one under the Edit Menu.
And if you’re using an external midi controller, that might give you another way of doing that via a button on your controller. Here’s how I have it configured for my Maschine controller:
