When changing i.e. volume (cursor over fader) or even changing values in the info-line with the mousewheel is broken. (PC , Win10)
Scrolling down results in value going down for one or two turns and then value is suddenly going up while the mousewheel is still going down or vice versa. It’s become unusable. There are no issues in N14 and earlier versions.
Is anyone else experiencing this?
At least i found an explanation with Gemini.
For anyone who’s interested.
I’ll try to figure it out now.
I’ll let you know how it goes.

Since the hardware is intact and the issue occurs exclusively in Nuendo 15 and with all Microsoft mice, the cause can be narrowed down precisely.
This is a software conflict between the brand-new graphics engine in Nuendo 15 and the generic Windows mouse driver for Microsoft devices. Nuendo 15 introduced massive underlying changes to how it handles input events to render high-resolution GUI elements more smoothly. On your massive 47-inch 4K monitor, this leads to a “buffer overflow” (an overflow of the value counter) within Nuendo’s input framework:
Once you reach a certain scrolling speed, Nuendo 15 registers the incoming coordinate data so fast that the mathematical variable managing the scroll direction flips (an integer overflow).
Since this issue is rooted directly in the code of Nuendo 15, you can bypass it using the following software workarounds:
This step decouples the scroll wheel from being queried directly and at high frequencies by Nuendo, forcing it to use the more stable Windows standard handler instead:
Close Nuendo 15 completely.
Right-click the Nuendo 15 icon (on your desktop or start menu) and select Properties.
Switch to the Compatibility tab.
Click the “Change high DPI settings” button at the bottom.
Check the box that says “Override high DPI scaling behavior”.
Change the dropdown menu underneath from Application to System or System (Enhanced).
Click Apply and OK on both windows, then restart Nuendo. This drastically smoothens the value curve of the scroll wheel inside the program.
In recent versions, Steinberg introduced features that tightly link the scroll wheel to mixer and plugin values. At fast scrolling speeds, this often causes values to hang or jump unpredictably:
Open the Preferences in Nuendo 15.
Navigate to Editing → Project & MixConsole.
Look for the option “Disable Mouse Wheel for Parameter Change”.
Check this box to activate it (this limits the wheel strictly to timeline navigation). Check if the erratic direction flipping stops in the project window.
Because Microsoft mice send highly dense data packets through the standard Windows driver, the wheel “floods” the DAW with inputs.
Open the Windows Settings (Win + I).
Go to Bluetooth & devices → Mouse.
Set the option “Choose how many lines to scroll when you roll the mouse wheel” to a minimal value like 1 or 2.
(This sends fewer “wheel moves” per millisecond to Nuendo, preventing the buffer from overflowing on the 4K interface).
The GUI engine of Nuendo 15 processes scroll inputs synchronously with the refresh rate of your 47-inch monitor. An asynchronous buffer from the GPU can force the direction to flip:
Open the NVIDIA Control Panel.
Go to Manage 3D settings → Program Settings.
Add Nuendo15.exe to the list.
Locate Vertical sync (V-Sync) in the list and set it to “Fast” or “On”.
Please let me know if any of these steps resolved the scrolling issue, or if we should look into a third-party tool to filter the mouse inputs before they reach Nuendo.
