@EmilAlipiev Could you attach a reproduction sample?. I have created a test trying to reproduce the problem, but without success.

Hi @jsuarezruiz
I think that it happens on certain cases. For example, using masterdetail page. I have added a repro attached.
please run the project in Android.
there 2 pages on the menu.
Select Page1 from the list... you will see that red line was drawn. If you click back button you go back to mainpage and when you select page1 again, it is gone. instead of backbutton, if you select mainpage and reselect page1, still same problem. so not related to backbutton also.

1+ on this bug, just discovered it in my application
Using Shell as navigation

I am having this problem too and my app is very close to release (about 5 days). Would be very nice if this could be solved asap!

I have the exact same problem with line and ellipsis and path object. When navigating in shell.

Still an issue. After switching pages in Shell ellipse simply disappears.

Equally hitting this problem. I have Ellipses in my main landing page. Noticed it when i integrated the AppShell with tab bar navigation into my app. The issue shows its ugly head when i navigate between tabs. once i return back to my main page, the ellipses have already disappeared :-(
