[Scale] button pressed with [Scale Factor] slider to the right of [Scale] button

SUMMARY
By default, when the [Scale] button in the toolbar is pressed, it produces a blue screen of uglyness in the viewport.

STEPS TO REPRODUCE
1. VNC Connect to either a Linux system or Windows system running TightVNC server
2. Press the [Scale] button on toolbar
3. 

OBSERVED RESULT
Blinded with blue screen of uglyness

EXPECTED RESULT
Add [Scaling Factor] slider to toolbar as shown in attachment to easily adjust scaling to properly view the remote host. I DDGed and saw a post from 2022 that shows something similar:

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  Manjaro Linux 24.2.1
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION
I think it would be helpful to automatically add the [Scaling Factor] slider to the right of the [Scale] button in the toolbar when the [Scale] button is pressed, and remove [Scaling Factor] slider when [Scale] button is not pressed.

Just some added info...

In the 
STEPS TO REPRODUCE
1. VNC Connect to either a Linux system or Windows system running TightVNC server

Not limited to TightVNC in my testing.

I use TightVNC[1] server on my Windows hosts (switching to TightVNC soon) and TigerVNC[2] on my Linux hosts. They both use their default settings, except for the connection password. Most hosts are on a secondary NAT network.

I was just updating to notify of host's VNC servers used. I don't know if this matters or not. Extra info never hurts anything.
