Atelier Rorona Plus The Alchemist of Arland [BLES02050]

I'm experiencing  random game breaking freeze with no sound, the only option is to close the game and restart. It happens pretty often but only during dialogues and synthesis. The log would just start popping endlessly the following lines of error:
E {rsx::thread} RSX: Failed to find section for render target 0xC79A0000 + 0x708000
E {rsx::thread} RSX: Failed to find section for render target 0xC6B40000 + 0x708000

Specs are:
i7-6700HQ 4-Core 2.6GHz
Nvidia GeForce GTX 950M 2GB
8GB RAM
OS Win10

The emulator is set on the following settings



I've already played with all of them and the results are the same every time. Also when Write color buffers is unchecked the game flashes missing textures as it follows.


Generally it has shown very good performances for me aside from this, slower on OpenGL  than Vulkan for me, and does not boot with D3D12. Also updating the Nvidia drivers to the latest recommended 390.65 WHQL makes the vulkan rendering option disappear completely from the emulator.
