I noticed this as well.
@corporateshark No repro on Pixel 7 Pro, probably we need to check on a device with Adreno 650
It's because we're always calling ICommandBuffer::present(), but EGL is doing this for us on Android. We added a shouldPresent flag to ShellParams so we can avoid this:
We haven't updated the sample apps yet to check this before calling present though.
