Steps to Reproduce

Issue can be easily reproduced on any example with surface shapes on textures.

Expected behavior: It should free allocated graphical memory on GPU friver level

Actual behavior: It creates a copy of texture on each frame and generates 1Gb VRAM leak per second.

Reproduces how often: Always

This issue is somehow related with the driver. Below are the hardware info from Galaxy Tab Active3 on Android 13 and Galaxy Note 9 Android 10.

First one has an issue, but second one is not.

I have created topic on ARM forum, but I think some workaround should be done on engine level.
