[Chip] Chips are blinking in ChipGroup with custom font

Description: I’m trying to update all Chips in ChipGroup but they are blinking for a short time.

Expected behavior: Chips update without blinking.

Source code: Chips are created programmatically:

    private fun createChip(context: Context, chipTitle: String): Chip {
        return Chip(context)
            .apply {
                setTextAppearance(R.style.ChipTextStyle)
                text = chipTitle
                isClickable = false
                isFocusable = false
                setChipBackgroundColorResource(R.color.chipColor)
                setTextColor(ContextCompat.getColor(context, R.color.black))
            }
    }

Style with custom font:

    <style name="ChipTextStyle">
        <item name="android:textSize">20sp</item>
        <item name="android:textColor">@color/black</item>
        <item name="android:fontFamily">@font/whitney_medium</item>
    </style>

Update method:

    private fun updateAllChips() {
        chipGroup.removeAllViews()
        val chipsTitles = listOf("Tag 1", "Tag 2", "Tag 3", "Tag 4")
        chipsTitles.forEach { title ->
            val chip = createChip(this, title)
            chipGroup.addView(chip)
        }
    }

@ymarian I wouldn’t say it is expected, because when I set custom font manually all works fine:

    private fun createChip(context: Context, chipTitle: String): Chip {
        val customFont = ResourcesCompat.getFont(context, R.font.whitney_medium)
        return Chip(context)
            .apply {
                typeface = customFont
                textSize = 20f
                text = chipTitle
                isClickable = false
                isFocusable = false
                setChipBackgroundColorResource(R.color.chipColor)
                setTextColor(ContextCompat.getColor(context, R.color.black))
            }
    }

I also encountered the flickering issue in version 1.2.1 when using a custom font, I updated to the latest version 1.4.1, and the flickering is now gone 😃
