Hi, I can’t reproduce it here, using the M1 plugin, I think this is the one showing.
Here’s something to try: Assign shortcuts to the commands Navigate-> Less and Navigate->More. While you have the browser open, try the Navigate->More and see what it can do (it will open the filters tab at least). Other than that, what happens if you drag the browser?
There seems to be a little window resizing handle at the bottom right of that window in your screen capture (at the very bottom of the part you’ve enclosed in a red outline). Can you make the window wider by dragging that?
I’m trying to find a way to reset Cubase settings just for ONE VSTi. Not sure if it’s possible. However, I can’t find a folder with that specific plugin window parameter. Something definitely went wrong.
