System Information
Operating system: macOS 14.0
Graphics card: AMD Radeon Pro 5300 4 GB

Blender Version
Broken: All 3.6 versions

Going into material preview mode or render view mode in Blender makes the viewport very laggy in new macOS update, 14.0.
Going into material preview mode locks/freezes Blender when CPU+GPU rendering mode is active.

Exact steps for others to reproduce the error
Open Mac
Download 14.0 OS
Open any 3.6 version of Blender
Make a cube or any mesh
Go into the Material Preview or Render Preview modes and manipulate workspace

@iss can you check on MacOS 14 + AMD?

Could be related to these:

Do you observe such problem in other software? How much was CPU/GPU usage and memory utilization?

Can not reproduce with 5700XT GPU. Can you perhaps make screen recording so I have better idea what to look for?

@PratikPB2123:
I have not seen lagging occur in any other software.
CPU and RAM usage was moderately higher than normal, approx. 30% higher.

I did a bit more research and realized that the lagging occurred when I was trying to render a specific type of file, namely a Mecabricks LEGO .zmbx file. Other file types so far do not cause lagging.

However, a new issue is persisting throughout all builds and all file types: EEVEE Depth of Field. This lags extremely heavily while in EEVEE material preview mode or EEVEE render mode.

Going to make a new issue for this.^^^

Can confirm lagging only occurs in .zmbx files.

Imported a 1 million tris .fbx, and imported it to Blender. There was a bit of lag in Render Preview, but it not nearly as bad as a .zmbx file.

We can close this issue.

Confirm: Issue is only in 3.6 and 4.0 builds. 3.5 works fine.

Thanks, closing.
Performance may not be good in heavy files. While we do continue to work on improving performance in general, potential performance improvements are not handled as bug reports.
