Bug: [Qt build] Controls are escalating – unusable

FMOD Studio
1

I switched to the new Qt based fmod Studio a while ago, and I have a huge usability issue which is probably a 1-minute fix for you.

When I drag a UI element like the volume knob, an automation point, or a parameter value, the value jumps in an uncontrollable way. When I gently slide the mouse down, volume jumps from 0 to 0 … to 0 … to -∞ dB! Even when I move the mouse down by 1 cm and then up by half a cm, the values still get more negative while moving the mouse up again.

In code, what very likely happens is that once I click, you keep those coordinates as x0,y0. When I drag the mouse down, for every mouse position xm,ym you move the value by the full delta to x0,y0 instead of by the delta compared to the previous mouse position.

This is still the case in 2.03.12 (Qt 6.5.3).

I’m getting desperate when having to do anything in FMOD except for arranging clips because of this bug, please fix this :slight_smile:

Thanks,
Simon

Hi,

Thank you for bringing this to our attention.

What operating system are you on?

A workaround may be manually inputting the values:

InputtingValues

Most values can be changed by double clicking on them, or clicking on the triangle next to some values:

Hi Connor,

Oh, so cool, I did not know you can double-click the values!

I’m on an Ubuntu 24.04.

Thanks for the tip, that already helps a lot!

Thanks for the info.

Are you remoting into the machine or using it locally.

I find that when remoting into Linux machines interaction with the dials can be slightly aggressive. However, when using the machine locally I am able to get more gentle interaction. This could be something we could address?
