Different slider/cursor behaviour on Windows and Linux

[rebio]

Short description The same action does different things on Windows and Linux

Steps to reproduce

1. Open RawTherapee
2. Open an Image
3. Adjust the image to your linking using any tool slider aka "use the software"

Observed behavior Windows:

• Left click: Slider position jumps to cursor
• Mouse wheel click: Slider position moves slightly toward the cursor position

Linux:

• Left click: Slider position moves slightly toward the cursor position
• Mouse wheel click: Slider position jumps to cursor

Expected behavior Works the same on both OS

Additional information Latest version of RT was used (3101)

Windows: Windows 10 with latest updates

Linux: Operating System: KDE neon 5.25 KDE Plasma Version: 5.25.2 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.5 Kernel Version: 5.13.0-52-generic (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 4800H with Radeon Graphics Memory: 30.8 GiB of RAM Graphics Processor: AMD RENOIR Manufacturer: Micro-Star International Co., Ltd.

Expected behavior Works the same on both OS = Works on Linux and Windows like it does now on Windows or on Linux. Left click and middle click do the same on both OS. No preferred default

And do you have any local settings.ini file with gtk-primary-button-warps-slider on either system set to true or false?

I checked

• /home/USER/.var/app/com.rawtherapee.RawTherapee/
• /var/lib/flatpak/app/com.rawtherapee.RawTherapee/current/active/

and

• /home/USER/.config/RawTherapee5-dev-AppImage/

for the AppImage dev snapshot.

I could not find any settings.ini file or a gtk-primary-button-warps-slider setting. Since I have never heard of it, it's very unlikely that I changed it.

Shift + Click on a slider does the same as middle click on Linux (the slider jumps to the position you clicked on)

I am using:

• Linux Mint 20.3 Cinnamon
• the latest build (5.8-3128)

In my Linux system, the behavior is exactly like you describe for Windows (Left click: Slider position jumps to cursor; Mouse wheel click: Slider position moves slightly toward the cursor position).

I can't test it in Windows.
