Hi,
We encounterd an error after the 2023 release :

with sometimes this warning :
2023-11-16 14:12:58 [573,059ms] [Warning] [carb] Client omni.ui has acquired [carb::svg::Svg v0.1] 100 times. Consider accessing this interface with carb::getCachedInterface() (Performance warning)

It’s happen when we run our workspace which include 5 cameras rendering and publishing ros2 rgb+pcd.
With one camera it works but with the five it crash.
On the 2022 release it works without problem.
Here is our setup : Ubuntu 22.04 with 64gb/ram
|---------------------------------------------------------------------------------------------|
| Driver Version: 525.85.05 | Graphics API: Vulkan
| GPU | Name | Active | LDA | GPU Memory | Vendor-ID | LUID |
|---------------------------------------------------------------------------------------------|
| 0 | NVIDIA GeForce RTX 4070 Ti | Yes: 0 | | 12528 MB | 10de | 0 |
|---------------------------------------------------------------------------------------------|
| 1 | Intel(R) Graphics (RPL-S) | | | 48048 MB | 8086 | 0 |
We will try a workaround by enabling/disabling ros2 publisher “on the fly” but I’m wondering if there is an issue somwhere with driver or anything else.
Thanks in advance and have a good day !
