[Button] Vertical bar appers and gone on the right of button and textview's

[kelalaka153]

This is a very strange behavior. I'm using bottom navigation and in one of the fragments (FA) there is a button. When the fragment is shown for the first time everything is normal. When we use bottom navigation to other fragments and then back to the FA, a vertical bar appears on the right of the button and then disappears in 3 seconds. This happens to buttons only with style using Widget.MaterialComponents.Button.OutlinedButton as parent style. Elevated is behaving as expected.

This is the style that the button uses

    <style name="ButtonTopGroupRight" parent="Widget.MaterialComponents.Button.OutlinedButton">
        <item name="iconPadding">8dp</item>
        <item name="fontFamily">@font/poppins</item>
        <item name="iconTint">@drawable/button_top_group_right_selector</item>
        <item name="strokeColor">@drawable/button_top_group_right_selector</item>
        <item name="android:textColor">@drawable/button_top_group_right_selector</item>

    </style>

Expected behavior:

Hi @kelalaka153,

Do you have a minimal sample app you can share with us that reproduces this? I don't see anything like this when trying to repro the issue on my end. Thanks!

I'm trying to minimize the code. need a little more time.

@kelalaka153 , I also saw this (a couple of months ago). I doubt it's been fixed in the latest 1.12.0 version of Material. I put android:scrollbars="none" on the views that were showing the scrollbars 😕
