Glitchy Resizing in Logic Pro on macOS Tahoe

[mardiqwop]

Hi, all.

My team is finding that our resizable plugins are not resizing properly in Logic Pro on macOS Tahoe. We think this is most likely not a JUCE issue, but we’re curious if others are experiencing this and if there are any workarounds.

Here’s a video showing the resizing behavior with the AudioPlugin example. The only modification I’ve made is calling setResizable(false, true).

It seems like during mouse drags, we’re getting inconsistent mouse deltas in ResizableCornerComponent::mouseDrag. While dragging the mouse down, the value returned from MouseEvent::getDistanceFromDragStartY is not consistently increasing, and will sporadically jump.

We are facing the same issue with some of our plugins but have not workaround yet. We agree that this is probably something Apple needs to fix in Logic or the OS.

I noticed that too.

Same here. macOS 26.2 + Logic Pro 12.0 still has this problem.

Checking back on this - has anyone figured out a workaround?

Also noticed this. Reported it here along with some other issues:

macOS Tahoe / Logic X: Mouse not respond after moving Window

It also happens with the demo plugin. It’s an M1 Arm system. Logic runs as an Apple Arm process: [image] Edit: The problem happens very consistent on my system when you move the window fast. For slow movements the window stays responsive most of the time. Edit: I could also reproduce the dead area problem at the bottom of the plugin: Plugin scaling is also not smooth. Looks like the UI size is jumping around while resizing: Tahoe 26.1 Logic 11.2.2 JUCE 8.0.10 and earli…

Also hope for a fix in Logic or Juce

Yes, I have also seen the mysterious bottom dead area issue seems like a dead rectangle area (of which the width is smaller than plugin window). No fix in Logic yet and I don’t think JUCE can fix this. Logic Pro 12.0.1.
