Extreme Slowness On Some Safari

[Jesse LaVere]

I have a simple react grid with the first three columns frozen.

This works quite well in Chrome and Firefox and on some versions of Safari. On other versions of Safari the app comes to a screeching halt and will pause for many seconds at a time before continuing to work. Clicking in the right panel or scrolling will often cause the issue to occur.

From what I can tell it's machine specific. Meaning, we have tested on the same version of Safari and on some machines it works and others the slowness is present.

Have you seen this before? Do you have any suggestions on how to fix?

Hi Jesse, 

Thanks for contacting Syncfusion support. 

Based on your update you have mentioned that on the other versions of safari the screeching halt and will pause for many seconds at a time before continuing to work. 

We have validated your query and suspect that the reported screeching halt issue may be related to safari browser or operating systems. So please share the safari browser version used in your machine to validate further on your requirement. 

Regards, 

Ajith G.

As I said, it's happening only on particular hardware. Meaning it works on some machines with safari Version 14.0 and fails on other machines that have Version 14.0

Safari Version 14.0
