Artifacts in image resources

Hi,
I've developed a Qt application as android apk for android platform.
But when I launch the app in android on one of the vendor boards, I could see one or other image resource being corrupted or some random artifacts on it.
I don't see the issue on mobile device or on the linux OS based platforms.
Could someone help in which direction to debug this issue?Thanks in advance.

What type of artefacts ?
What type of image ?
What properties of the image ?
What type of device ? -

Hi,
What version of Qt ?
5.12.2
What version of Android ?
Oreo/Pie
What type of artefacts ?
blue and green pixels/dots or images rendered broken sometimes
What type of image ?
any png/jpeg resource
What properties of the image ?
not clear..what do you mean by properties of image here?
The memory/size of the images varies between 0.5kb - 2.5kb only.
What type of device ?
it's an embedded device with TI J6 chipset with Arm A15 processor .Please let me know if you would like to see a screenshot.

Yes, that would be nice.

Intriguing...
On what device does this happen ?
Can you compare that with a tablet or smartphone running a similar version of Android ? -

It's an embedded device with TI J6 chip set running Arm A15 processor and SGX544 gpu.
I didn't get your question. Like compare what?
Any specific logs? or the behaviour?
I've already tested it on multiple tablets and phones with similar Android version and there were no issue on them. -
Ok, so it could be something that is hardware specific. Do you have only one device ? If not, does the issue appear on the other device ?

Yes I've tested on another device with similar specs having Arm A15 processor and SGX544 Gpu, I see same issue there too but with low frequency.
I've tested on several mobile devices, but I've never seen such issue on mobile devices.
I've also tested same app developed with java , but i don't have artifact issue with those apps. The issue here is seen only with the Qt based android app.Could it be any graphics/openGl issue? Do you know any debug logs that could be enabled for verifying the rendering/graphics of images in Qt?
Thank you. -

There's one more observation that I had tried yesterday.
So if I load the image resources one after another after a certain delay let's say in window of 4-5 secs, the artefacts frequency is reduced and is visible only at a frequency of 2/10 times.
Could it infer something? -
I looks like its something specific to that device.
Do you have its specification somewhere ?

Are you using one of the evaluation board ?
