Type: Bug

Problem Description:

After updating Visual Studio Code, smooth scrolling stopped working when the editor zoom level is set to 125%. Resetting the zoom level to 100% resolves the issue, but the problem reoccurs when returning to 125%.

Steps to Reproduce:

1. Ensure the following settings are applied:

   {
       "editor.accessibilityPageSize": 14,
       "editor.fontLigatures": false,
       "editor.mouseWheelScrollSensitivity": 2,
       "workbench.list.mouseWheelScrollSensitivity": 2,
       "editor.fontFamily": "Consolas, Cascadia Code, SF Mono, 'Courier New', monospace",
       "workbench.colorTheme": "One Dark Pro",
       "go.toolsManagement.autoUpdate": true,
       "workbench.list.smoothScrolling": true,
       "editor.smoothScrolling": true,
       "terminal.integrated.smoothScrolling": true,
       "editor.cursorSmoothCaretAnimation": "on",
       "editor.cursorBlinking": "phase",
       "editor.fontSize": 15
   }

2. Set the editor zoom level to 125% using Ctrl + = or View > Appearance > Zoom In.
3. Try scrolling in the editor.

Expected Behavior: Smooth scrolling should work correctly at 125% editor zoom level.

Actual Behavior: Smooth scrolling is enabled but does not work in both the text editor and the terminal. Scrolling is jerky, as if smooth scrolling is disabled.

agreed

I've found a workaround that might work for some people:

If you enable editor.mouseWheelZoom you can set the window.zoomLevel to 100% (which isn't that bad)(which is called 0 in the settings and 125% is actually 120% and is called 1) and then enlarge the editor font with Ctrl + MouseWheelUp.

I think I'll stay that way permanently, because I can now see more tabs LOL

Thank you a ton. Had no idea that 125% scale had to do anything with scrolling, but just checked and it was in fact true in my case too. Very weird bug.

[asifrahaman13]

In my case

"window.zoomLevel": 1

caused no smooth scroll. but whenever I changed this to floating point number above 1 it worked.

"window.zoomLevel": 1.01,

Strange bug.
