So i was adjusting the volume, and I hit escape before I released the mouse.
Then, the sound kept going up and down, as my mouse moved from left to right.
I went back to the settings menu, and found that the slider was still moving with my mouse.

How to replicate.
Step 1: go to the settings menu.
Step 2: Press and hold down mouse over volume or graphics slider.
step 3: press escape on your keyboard.
step 4: move mouse.
step 5: release mouse button.
This isn’t really game breaking other than adjusting the graphics level, and this bug occurring would slow down your ROBLOX client.
