I'm wondering if anyone else has come across an issue where column sizes in K2 Listviews are going nuts when using the designer via chrome. I have a view that renders well in runtime and hasn't been edited in months and suddenly column widths are showing over 600% each. as a consequence to this, you are not able to drag column sizes by using the line between each column cos it is rendering the area where you can click as "over 600% to the right" i.e. well out of screen range.
This issue isn't happening while using edge.
Nintex is aware that the recent Google Chrome update seems to have caused this behavior. We are investigating now to identify solutions and workarounds.
In the short term, if you can use MS Edge, you should be able to continue designing your forms.
