Bug 265123 – Mac Catalyst mouse scroll issue

• Status: NEW
• Component: Scrolling

[Cedric]

Hello,
I’m having a vertical scroll problem with mouse that doesn’t work randomly on the Mac Catalyst version of the app (build with Ionic Framework).
Everything works perfectly on iOS with touch, and on Mac I can make the scroll work if I use the trackpad (same issue if I use iPad with a mouse).
On Mac it seems random, sometimes it works sometimes not. Sometimes quitting and relaunching the app is enough to make the scroll work again with the mouse (and without doing anything other than quitting and relaunching the app), sometimes it works again just by manipulating the app.

The scroll bar works fine, however, so I’ll just click and drag with the cursor on the scroll bar.

It worked perfectly at the beginning and the problem has appeared since the latest macOS / Ionic updates.

Does anyone have this problem or can help me with it?

Thanks
