UWP app on Windows IoT Core renders image wrong

Hi,

Runtime creating some images on a XAML page (as children of a canvas), assigning a BitmapImage as source. Occasionally the images (which are rather small) show partials of other images from within the application. After a redraw, the images are rendered correctly again (based on the same PNG files, running through the same code).

Sample with random wrong images:

Checked the resources on the Raspberry PI 3b but memory is only at 40%. And it does not happen all the time, so no reproduction path available.

Hope someone has a clue.

KR, Dick

Hello,

Does this problem happen randomly only on Raspberry Pi devices with Windows Iot Core? Will you encounter this problem when deploying this APP on local machine or other devices? May I know the version of Windows Iot Core you are using.

Hi @Criszhan-msft ,

Sorry for the late reply, did not notice your prompt response.

I have not seen it happen on regular Windows 10 systems so far, only on IoT core. We are using build 17763, which works great for our software except for the random glitch in image displaying.

Hello Dick,

It seems that this is a random error that cannot be reproduced accurately. When you say that running this app on your local machine has not had this problem yet, it seems to point to the specific system or device, not the app itself.

Also, does this problem only occur on one device? Or multiple RPi 3b devices with windows IOT Core (17763) running this app all have this problem.

Best Regards,
