You might have a look on #969 (windows case)

If you are using AMD's iGPU and Nvidia's dGPU, you can try running launcher through the console with those flags:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia gdlauncher

You can also modify the gdlauncher.desktop file to use the flags automatically:

Exec=env __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia /usr/bin/gdlauncher --dummy-flag %U

These flags require nvidia and amdgpu drivers
Maybe these flags work with Intel's iGPUs as well, but I have no way to verify it
