DPi Scaling 150%-350% sample plugin rendered incorrect vertical sizing

[pebble]

I'm a plugin developer.
I would like to report a GUI scaling issue observed on Windows and Studio One.

When using Studio One with the system display scaling set to 225%, the GUI of the sample plugin `again.vst3` included in the Steinberg VSTSDK.
plugin does not render correctly. The layout appears distorted, with incorrect vertical sizing.

The issue occurs only at specific DPI scaling values.
100%:Good
125%:Good
150%:Bad
200%:Good
225%:Bad
250%:Good
300%:Bad
350%:Bad

Environment:
OS: Windows11 Pro 25H2
DAW: Studio Pro 8.0.3 (Latest)
Display: LG 4K Monitor 3840x2160
VSTSDK3.8.0

I am NOT a developer (so can't help in any way to help you to resolve the issue), but the obvious question that has to be asked is whether you have tried the plugin in any other DAW than FSP in the same Win11 environment at the problem scale factors (realistically could be a windows issue, or a graphic card for that matter?)

Are you actually coding plugins by hand in a real language like C++? Or are you using a framework like JUCE?

Cubase15.0.20 has no problem in same environment.
again.vst3 uses VSTGUI(in VSTSDK3.8.0) not JUCE.

Hiya,
Is this plugin available for download and can you provide a link to where it can be downloaded from, please?

To my mindset, this is a question you might need to ask FSP support for help with, this looks like a very specific developer question and you are asking the question in a user forum.

Kindest regards

Thank you for the info. QED
I had a tootle around the net and came across the following. It appears some CBase user's are having difficulties with this item as well

Plugin AGain?

Hi, On my Macbook I have a plugin with the name AGain Plugin, Steinberg. Is it some one who knows where I can find it and deleted it?

I can safely assume that this is some kind of template from the SDK, and therefore your question would be better placed by logging a support ticket.

Kindest regards
