Slow framerate and shuttering in Droidian (Mobile GNU Linux)

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

I've manually compiled RetroArch in Droidian, a mobile GNU Linux distribution running with libhybris and halium. This has been done because flatpak's refused to work for me due to a OS issue.

While inside Waydroid, an android container for linux the emulation works perfectly fine, on Droidian it shutter a lot and the performance is bad.

Tested with a PPSSPP core from christianhaitian/retroarch-cores. Couldn't find any official cores for aarch64 linux.

One note. PPSSPPSDL works just fine on the same device.

PPSSPPSDL was compile using

cmake -DUSING_GLES2=ON -DUSING_X11_VULKAN=OFF -DUSE_FFMPEG=OFF -DUSE_WAYLAND_WSI=OFF .

Expected behavior

Running with GLES V3, should probably make use of the device's driver.

Actual behavior

Slow framerate and shuttering

Steps to reproduce the bug

Compilation on Droidian:

sudo apt-get -y install build-essential libxkbcommon-dev zlib1g-dev libfreetype6-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev libavcodec-dev libsdl2-dev libsdl-image1.2-dev libxml2-dev yasm libv4l-dev libsdl2-2.0-0
git clone https://github.com/libretro/RetroArch.git
cd RetroArch
git submodule update --init
./configure --disable-x11 --enable-wayland --enable-v4l2 --enable-pulse --enable-sdl2  --enable-threads --enable-ozone --enable-xmb --enable-materialui --enable-opengles
make -j3 ( Redmi Note 9 Pro 3 works file without crashing phosh)
sudo make install

Version/Commit

master / 74d0dd16fb5729bfe254194cff637f57049b7a30

• RetroArch: master

Environment information

• OS: Droidian
• Compiler: make

Start by reproducing the reported master build on Droidian using the listed configure and make commands, then compare its GLES behavior with Waydroid and PPSSPPSDL on the same device. Investigate the RetroArch rendering path involved in the GLES and Wayland configuration, and consider the issue complete only when the cause of the slow framerate and stuttering is identified with supporting test or bisect results.
