tl;dr Ardour give the UI scale to the plugin. And the plugins seenm to do it twice.
I can't even change the ui zoom in Surge.
Also 150%, I get the black window.

Just to clarify, the above screenshot is NOT edited. The crop was taken as is.

I think this is an issue on Ardour end, as I don't think we see the same behavior in any other VST3 host.

(By the way, you can right-click in the background of the GUI to get the main menu of Surge, which also has the zoom options.)

i'll find some time to download ardour 8 and try hopefully before christmas

sounds to me like it is sending me the vst3 setting for screen pixel scaling as its internal scale.

I just installed Surge XT 1.3 on Arch Linux (via pacman), using it with Ardour 8... discovered the same thing. It's so huge it won't fit on my screen. But I also noticed none of the zoom or shrink settings do anything at all, even trying to enlarge it. I also noticed that it has the option "Set Current Zoom Level (250%) as Default" and "Set Default Zoom Level to..." brings up 250 to start with, and setting it to a different number won't change it. So it's obviously stuck at 250% zoom.

Another thing that it's doing is when I bring up the menu and move the mouse between selections, the Surge UI completely disappears and only the menu is visible. Not sure if that is related.

I really really think this is a bug in Ardour...

Might this bug be related?

Ardour: VST3 Plug-In GUIs cannot be resized smaller than the size at the most recent project save

It's the most recent bug I can find that looks at all relevant on Ardour's bug tracker. It's been open since 2021. I have not tried the workarounds suggested but will.

In the meantime, setting Ardour GUI scale back to 100% and restarting makes Surge's GUI zoomable again. Tweaking presets in tiny Ardour and then using them in readable Ardour is somewhat cumbersome, but since they both do exactly what I want otherwise, that is what I have been doing.

I'd be grateful if you all could talk to the Ardour devs about this when you have a chance. I do not have the resources to argue-- or, um, discuss this with them. Making noise/music is much more life-affirming. :)

I suppose this means we could probably close this issue if it's confirmed on Ardour's end (which was my suspicion from the get go).

@baconpaul Thoughts on the above?

[baconpaul]

I was going to test it next time i was in linux. Lets leave it be open for now on the odd chance that up upgrade to juce 7.0.12 for #7640 also helps
