@Sasha55678568 - I assume you are referring to the steps in which the Miro board zooms. However, how are you doing this? Wheel on a mouse, laptop trackpad, Ctrl/Cmd +/- shortcuts? The Miro board’s +/- zoom buttons in the bottom-right corner?

Also,

• Are you Windows or macOS?
  • Have you tried adjust any mouse wheel/scroll settings in your OS?
• Are you using Miro in a browser or a desktop app?
• If a browser,
  • which one?
  • have you tried disabling all browser extensions?
• Have you recently installed/had update mouse software updated, e.g., Logitech?

I am using Windows 10 64-bit (Home at home and Pro at work) and have not noticed any change in zoom steps/scale of my zooming in Chrome, Edge, or Firefox, or in the Miro Desktop app.

@Robert Johnson I have Windows. I did not change anything in the settings and the mouse is the same. Before that, I really put the mouse from Windows, but now I work the same as always. When I change the scale using + and - the scale changes as before, smoothly.

@Robert Johnson  but still it doesn’t work correctly because I can’t use my mouse for scailing

@Sasha55678568 - You never responded to my question of “which browser” you are using. If you are using Firefox, there is currently a known issue with zoom/scaling in Firefox:
