Expansion states, overrides, and load masks are stored as "data blocks" on the LOP Network. Data blocks are removed like this:

s = hou.node('/stage')
s.removeDataBlock('foo.overrides')

The warning is coming from the PNG library. It should be safe to ignore, however if you want to remove this warning, you will need to remove the offending profile. If you have ImageMagick, you can run: mogrify my.png

Sorry to dig out this old thread ... but has there been any progress on this? I'm struggling quite a bit with character light rigs and camera animations and wondered if there might have been something in 20.5 that I have missed.

So, the OpenGL multi view isn’t lagging and crashing anymore that’s what I meant.

Previously, when you split the viewport into two, (I don’t mean two displays, just creating two scene views) using one for XPU and the other for scene manipulations, there were frequent random crashes. Now, I haven’t been able to make it crash at all.

As for materials randomly turning black (Labs - reset viewport triggers this too), I’ve found a temporary solution. I create a second material, 'usd_preview_material,' and set its Purpose to 'Preview Render' when assigning it to the object.

Thanks for the answer! I'll take note.

P.S. Now I'm absolutely sure of Blender's bright future.

SideFX in version 20 introduced many cardinal internal improvements, which should lead to a noticeable increase in productivity, as I understood from the streams. And all the plans look very tasty, but apparently the new configurations turned out to be too buggy. And they are debugging them little by little. Let me remind you that the unnoticeable for users rewriting of SOP took several years and led to a cardinal improvement in speed. So the work is underway.
