I want to use two display windows in the Solaris system, one for operation and one for rendering. However, whenever there are two windows, there is an issue with material display, and the USD model turns completely black. This bug hasn't been resolved for a long time, which is really annoying. Will this bug be fixed in H20.5?

did you submit a bug, and if so, does it say 'fixed -- signed off' under status with a note that it will be available in 20.5?

This problem has been fixed in Vulkan viewer mode by setting environment variable HOUDINI_VULKAN_VIEWER = 1

But Vulkan mode has many limitions right now?

I think opengl will be replaced by vulkan next one or two main release,just like mantra and karma.
