  We have seen on large grids specially with many columns that the row selector and actual row cells become un-synchronized when scrolling on both IE and Safari, we have been unable to detect this issue with Google Chrome.

  I have attached a video showing it on Internet Explorer, this is a grid with a single column having this issue, the issue becomes worse and worse the more columns are displayed.

  I have also attached the JSFiddle used to create this video.

  Hello I am facing a simular issue here on the latest version of Safari (14.1 (15611.1.21.161.5, 15611)).
  
  The headers of the grid is not in sync with the content, sometimes the grid remains blank (or parts of it) until the user clicks on the grid too.
  
  The issue is happening even in the demo pages of wijmo.
  
  https://www.grapecity.com/wijmo/demos/Grid/Overview/vue.
  
  There is a video attached that demonstrates the problem on this page.

  Thanks in any advance.

  Hi Eduardo,

  I can observe your issue in the video but I am afraid I was unable to replicate it at my end. You can refer to the video link below:

  https://www.dropbox.com/s/ubnfp1bsbde65ku/Untitled.mov.zip?dl=0

  And this is the device that I used:
  
  Device: MacBook Pro
  
  OS: macOS Big Sur
  
  Safari: 14.1

  Can you please let us know your exact device which you are using so that I can test it?

  Regards,
  
  Ashwin

  Hi ashwin,

  Hi Eduardo,

  Thank you for providing the device info. I will test them on these devices and will update you accordigly.
  
  In the meantime, can you check whether only this demo causes this issue or even a simple FlexGrid causes it?

  ~regards

  Hi Eduardo,

  I wasn’t able to replicate the issue in the provided device also. This was the device which I used:

  

  But I have enquired about this issue with the dev team. Maybe they will be able to replicate it or provide some workaround. The internal id of the case is WJM-20030.

  I will update you once I will hear from them.

  ~regards

  Hi Eduardo,

  This was a major bug in Safari and the Apple team is working on the fix. Meanwhile, you can use the fix provided in the sample below at your end:

  We have also released a new version (5.20211.794) of Wijmo which includes this patch.
