Zoom and panning oversensitive with trackpad

I believe the zoom intervals are a representation of your computer's operating system settings. I have no experience with Apple/MacOS, but I believe that in Windows, this is somewhere in system settings > Touch pad > Pinch to zoom(?) or in your 'Line numbers to scroll' using the wheel on a mouse. I can remember the exact settings as I'm not near a computer at the moment, but essentially it should be somewhere in your OS settings and not Miro. My number of lines to scroll was at 3 or 5 in Windows 10 and once I lowered it to 1, when I scrolled the wheel in the mouse while in Miro, it zommed in/out at lower increments.

@Rob Johnson I can’t find the setting your talking about (I’m using windows).

Also, I’d be surprised that this would fix it as I don’t have any issues in other programs, but just in case would you be able to try and find the exact location of the setting you’re talking about ?

@Rob Johnson Ok sounds good, I’ll reach out to support.

Thanks for your help anyways !

Thank you for your answer, unfortunately, I have the same problem, and all my colleagues as well. We use the “Mouse” navigation option instead, even if they would have preferred “Touchpad” with a mouse connected, had it worked correctly.  

Changing the scroll settings in Windows works, but then the scroll step is too small on other apps like Outlook. It feels like Miro is the exception here - Ctrl+scroll zooms in way too much.

I’m using Windows 10 1809, bluetooth mouse. The problem occurs in both desktop app and website on chrome. 

I ran into a very related issue on a macbook. Zooming in with CMD+Scroll Wheel would jump unhelpfully between 400% and 36% (I think that’d be CTRL+Scroll Wheel for Windows users). However, if the app detects that I’m using “Mouse Navigation” automatically… then just using scroll wheel (without any key modifier) will scroll much more smoothly.

Unfortunately, I had to override the “Auto Switch” Navigation device option to always be “Mouse” to consistently treat scroll wheel as zoom. This seems to be the only way to get a sensible zoom step on my macbook when a mouse is plugged in. I think Miro detects that I have a track pad present, and “Auto switches” to “trackpad” for some reason. I’m not sure if this is a bug, or something to do with my hardware and dock setup.

My preference would be to always allow CMD+Scroll Wheel to function as this more sensible zoom step regardless of the Navigation Device option, as that keyboard shortcut is what I’m used to from other 2D drawing platforms (CAD mostly), and it’s current behavior isn’t that valuable. Unfortunately, that likely won’t be to everyone’s taste so my ask is likely a full-blown navigation preference section with customizable keybinds………………. :(

TL:DR The workaround is to make sure your Navigation preferences are set to “Mouse”, and DON’T press CTRL or CMD when scrolling.

I tried the above suggestions of switching Navigation settings on my MacBook from `Auto-switch` to just `Mouse` but the zoom scrolling is still too sensitive for me.

I wish there was a setting to adjust the mouse sensitivity. I could see the need for this to be different depending on what kind of board you’re working on.
