A Chrome Problem Solved - Curves disappeared with button down

With a recent upgrade to Chrome Version 120.0.6099.71 I was experiencing an annoying glitch. If I held down a button and tried to move a curve then all curves on the page would disappear. My curves are being plotted with scattergl and sgm. There are many curves and much data…

When I tried same page on Edge, the curves worked fine. I was almost resigned to uninstalling and reinstalling Chrome but instead first I went to C:\Users<me>\AppData\Local\Google\Chrome\User Data\Default and deleted every directory with the phrase “cache” in its name. There were a lot of javascript files, and other stuff.

And amazingly, that did the trick. Thought I would share in case anyone else stumbles into same problem.

[Edit:: not solved, issue has come back :frowning: ]

This seems to be a plotly bug. The problem has gone away by rolling back to 2.22.0 from 2.27.0

I have not investigated which of the releases broke the scrolling… something for next year (if it isnt already fixed by then)
