The background color of the grid cells may not change
« on: June 25, 2020, 10:22:28 am »
Hi,
I have an issue where selecting a cell in the grid does not change the background color.
Normally, selecting a cell with the mouse changes the background color, but in some rare cases, selecting the cell after scrolling the grid does not change the background color.
This phenomenon occurs in all dateType cells.
The frequency of this phenomenon is about once for about 30 operations.

Please tell me the cause of this phenomenon and the measures to prevent it.

Is this going to take some time to resolve?
If the question is not clear, we will ask you again.

Thank you for your answer,

Although it is a browser, crome version is 83.0.4103.116.
The frequency of this phenomenon is fairly low.

I was able to reproduce it on the demo site below.

The operation is to select cells while scrolling with the mouse several times.
Then, the phenomenon that the background color of the selected cell is not colored occurs.

The attached image is a screenshot when the background color does not actually change when selected.

Is this a bug that cannot be reproduced or is difficult to solve?

I'm unable to reproduce anything unusual.

You need to ensure that scrolling stops completely before selecting any cells.
