Issue on the view "planning - by: dnaton

Hello,

I remark since a few days (maybe since update to v6.0.5 but I'm not sure) that I have an issue in the screen "Planning", in all my projects :

The "gantt display" on the right on the screen works fine at the beginning, and is "synchronized with task on the left of the screen.

And suddenly, there is a misalignment between task and gant

Here is an exemple



How is it possible to correct the problem ?

Thanks
