Glmark2 Rendered Frame Size issue #196

Open

Hi,
We are trying to run the glmark2 (01_2023) version with the following command:

glmark2-es2-wayland --off-screen --size 640x480 -b texture:nframes=1:texture-filter=nearest

When we checked the total read/write bytes for this command using the perf counters, we get following data:
read bytes: 26271168
write bytes: 734640

Questions:

Why the total write bytes are less than the size of rendered frame: 640x480x4 = 1,228,800 Bytes

Thanks for any inputs.

Regards,
Madhav
