Thanks for reporting this - I think this could be an issue with the playground and not the Slider component itself, as it doesn't repro in the Slider demos here
The component for the playground is here - would you be interested in investigating this further? @yassinmars

Thank you for your response and guidance @mj12albert - yes absolutely i would like to investigate the issue further, i have already located the code for the playground and I'm currently looking through it to pinpoint the exact cause of the twitching issue. I'll share my findings as soon as I have something concrete.
from material-ui.
@mj12albert, I believe I've identified potential areas that could be causing the twitching issue with the Slider component. Here are my key observations:
-State Management in handleChangeShade:
This function updates several state variables simultaneously ([name]Shade, [name], and [name]Input). The frequency and scope of these updates might be causing the component to rerender inefficiently, leading to the twitching observed, particularly near the 100 and 50 marks. Here's code for reference:
-Dynamic Styling Calculations:
The Slider's sx property involves dynamic calculations that might be affecting its rendering performance. Reducing complexity in these style calculations could potentially improve performance. Hereβs the relevant code:
I'm currently exploring optimizations in the handleChangeShade function to reduce the number of state updates and simplify the dynamic style calculations. These changes might help in achieving smoother interactions with the Slider.

@mj12albert, I've implemented several optimizations based on the initial observation to address the issue. Here are the changes and the solutions i came up with:
- Optimized State Management in handleChangeShade:
I refactored the handleChangeShade function to minimize the number of state updates and potential re-renders. By consolidating the state updates into a single setState call, we reduce the overhead and improve the slider's responsiveness. Here's the revised code snippet:
- Simplified and Improved Slider Styling:
To further enhance performance, I simplified the Slider's dynamic styling by moving the style calculations outside of the component render method. This approach minimizes recalculations and leverages CSS for better performance. The updated styling I applied is as follows:
- Integrated Changes within colorPicker Function:
I ensured that these changes were integrated smoothly within the colorPicker function, keeping in mind the overall component structure and existing functionality. The focus was on ensuring that the modifications did not introduce any new issues or regressions.
Here's how the modified section looks now:
