Hello,

I've run into an issue where my Row Horizontal Grid Line is disappearing when I have many columns. I am not changing any styling. I do have Row and Column virtualization on though.

The issue occurs when I add at least 834 columns, not sure why 834 and that number could be higher if other environments. If I add only 833 columns to the grid the Row Horizontal Grid Line appears just fine. If I add 834 columns or more, the Row Horizontal Grid Line is gone.

Is there anything I can do to make sure that Horizontal Grid Line always shows?

Thank you.
