Bug description:
We are currently working on enabling GNOME (Wayland) to run on top of
a Imagination GPU hardware accelerator for RISCV64. Initially, we
tested this on Ubuntu 22.04 LTS, but after receiving suggestions from
the GNOME forum, we decided to switch to Ubuntu 24.04 LTS. Since
upgrading, we've noticed significant improvements, and GNOME is
running more smoothly than expected. However, the graphics
configuration still shows "Software Rendering" instead of utilising
hardware acceleration. Despite configuring the Imagination GPU, we are
unable to enable hardware acceleration for GNOME, which is impacting
3D rendering performance.

Please find the below EGL logs details for Imagination GPU as below:

OpenGL ES profile vendor: Imagination Technologies
OpenGL ES profile renderer: PowerVR Rogue GE8300
OpenGL ES profile version: OpenGL ES 3.2
OpenGL ES profile shading language version: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

After several attempts and experiments running GPU computing tests,
such as OpenCL tests on the Imagination GPU, an issue arises when
attempting to execute 3D programs[opengles], as they are being
executed on the CPU instead of the imagination GPU.
