Hello.

We are currently developing using Unreal Engine 5.5.4.  
During playing, we encountered a crash that occurs only on devices with **PowerVR GE8320** when change screen orientation.  
The crash happens in **glBlitFramebuffer()** during screen rotation.

The occurred devices :

- Realme C2 (RMX1941) – Android 9, OpenGL ES 3.2 build 1.10@5130912
- Oppo A78 (CPH2483) – Android 12, OpenGL ES 3.2 build 1.10@5130912

Below is the crash backtrace that occurred when playing the engine template project with the OpenGL renderer on the Realme C2.

Hi liiyuu,

Thanks for your message, and welcome to the PowerVR Developer Forum!

The GPU driver version reported (1.10@5130912) is really old and there might be a possible driver issue. Unfortunately Imagination Technologies does not decide what GPU driver version runs on retail devices, but the SoC manufacturer does.

You might want to reach the SoC manufacturer in this regard, in case they are considering to update the GPU driver for those devices.

Best regards,  
Alejandro

Hi AlejandroC, thanks for your reply.

First of all, our game targets support for a variety of devices with PowerVR GPUs. So we’re looking to properly address the issue.

Before contacting SoC manufacturer, we’d like to get a clearer understanding of the root cause of the driver issue. Could you help us investigate this further?  
Also, if this is a known issue limited to specific driver versions, we’d appreciate any insights on potential workarounds.

One more thing we found is that the issue does not occur on this device.

- Galaxy A12 (GE8320) - Android 11, OpenGL ES 3.2 build 1.13@5776728

Hi SeongbeomJeong,

Thanks for your message.

If the issue does not happen on a device with GPU driver version 1.13@5776728, I advice you consider this as the minimal version to allow your game to run. It is an old driver version as well. Many retail PowerVR devices will still have that version or a more recent one.

Best regards,  
Alejandro
