Verified this on Visual Studio Enterprise 17.8.0 Preview 1.0. Repro on Android 13.0-API33 .NET 8, not repro on iOS 16.4 with below Project: MAUITabBarProblem.zip
I'm having the same issue on Windows. Any solution or workaround to fix this?
What does this Animate flag do anyways? I don't see a difference...
My workaround for this is to force a dark theme natively in the Android app. In Platforms\Android\MainApplication.cs, insert in the class constructor the line: AppCompatDelegate.DefaultNightMode = AppCompatDelegate.ModeNightYes;
A simple fix for this might be for the transition animation to force a black background regardless of whether the theme is light or dark. That would mean the animation always showed a black border around the screen for page transitions. In a dark theme, the eye would not notice the border. In a light theme, the eye would see the border as background against which the new page expanded to full size. The appearance would look normal.
Description
Shell page transition causes a severe color blinking, especially for a dark themed application. It looks like the application uses default, light system theme when entering the page and then applying currently selected theme from application. See the gif below. The white blink is visible on the entire screen, furthermore the tabbar color transition from white to black is visible as well.
Occurs for both navigation invocation:
await Shell.Current.GoToAsync($"//{Routes.WelcomePage}", false); await Shell.Current.GoToAsync($"//{Routes.WelcomePage}", true);
Tested on .NET: 8.0.100-preview.7.23376.3 MAUI: 8.0.0-preview.6.8686 and 8.0.0-preview.7.8842
In my opinion, expected behaviour is to either apply theme changing once it is triggered and do not invoke such color transition animations during further page transitions or add Shell navigation parameter to enable/disable the animation. Currently existed Shell.Current.GoToAsync "animate" parameter seems not to be respected at all.
