I'm currently running a trial of Blazor UI, taking a look at the Grid and Virtual Scrolling. I've noticed a fairly heavy performance issue on chromium based browsers, bad enough that I wouldn't be able to release to production in it's current state. My project is Server Side Blazor and the performance issues seem related to mouse over/move, my grid currently only has a single item in it so no actual scrolling happening. I've tried with asp core 3.0 and 3.1 preview.
Firefox and MS Edge 44 runs the page just fine.
CPU usage for the Tab is very high during mouse movement and when taking a look at the browser tools Performance profiler a very long amount of time is spent Recalculating Styles and Updating the Layer Tree as attached.
Anyone had experience with similar issues or know of a fix?
