UI rendering problem on Huawei Ascend P6

Bug Reports
1

I created an empty project with few tags in main file “MainView.ux”:

<App>
    <ClientPanel>
        <StackPanel>
            <Text Value="test 2" />
            <TextBox Value="t" />
        </StackPanel>
    </ClientPanel>
</App>

I built the app for Android with both preview and build flags and ran it on Huawei Ascend P6 and I got strange rendering problems, though it works fine on P8 (Android 6) and other Huawei phone (Android 4.2.2) and local preview.

With preview flag:

Ouch! Definitely looks like the Vivante GPU / drivers in the P6 are causing us some trouble.

How does it look if you add an explicit rectangle inside the TextBox, like this?

<App>
	<ClientPanel>
        <StackPanel>
            <Text Value="test 2" />
            <TextBox Value="t">
            	<Rectangle Color="Gray" Layer="Background"/>
            </TextBox>
        </StackPanel>
	</ClientPanel>
</App>

It would look like this:

Though when I tap on TextBox briefly noise shows up on gray area while keypad is opening. And background noise under Text element changes.

Thanks. I’ve raised a ticket for this and we’ll investigate further.

It seems that there is issue in GPU driver. May be some driver programs/files get corrupted that’s why this annoying issue happen. So before trying anything more, i hardly recommend you to check driver status. If they are latest and updated then its ok…if not, then update them immediately.
