BEAGLEY-AI: PowerVR BXS-4-64 Diagonal Stripe Artifacts in Qt Quick (eglfs + GLES3.2)

Part Number: BEAGLEY-AI

Tool/software:

Hi,

In some Qt Quick examples I see artifacts on my HDMI display. If I run these examples using software backend (QT_QUICK_BACKEND=software) they run properly.

I put screenshot of Qt's keyinteraction example runned on my BeagleY-AI above. I got this screenshot using kmsgrab and this is what I exactly see on the screen.

This is how it should look like. I think those stripes are not random and have the same color as the background.

Software Versions:

I run these examples on my custom Yocto distribution. It has no X11. So all examples are run with eglfs platform. I had no issues with kmscube and rgx_triangle_test. These stripes only appear on some Qt Quick applications. I see them on both Key Interaction and File System Explorer examples.
