How to disable preview in Gmocappy

Hello. I'm loading huge files (230Mbytes size) and on my cnc desktop rendering of these files are useless and it's painful for working.
Is there a way to completely disable rendering of tool path, and don't burn CPU resources?
 

You can try to hide it, but I am not sure if this reduces the cpu load (and if its even hidden). Insert this in the display section of the ini file:
EMBED_TAB_NAME = preview
EMBED_TAB_LOCATION = ntb_preview
EMBED_TAB_COMMAND = hide
For reference:
linuxcnc.org/docs/devel/html/gui/gmoccap...tabs-and-side-panels

add this near to top of program:

(AXIS,stop)

If I use "EMBED_TAB_COMMAND = hide" on 2.9 it hides the preview but also the file browser. I guess they display in the same "tab"... or something.

Meanwhile AXIS,stop seems to speed things up, allows big (15MB) gcode files, but I get this error:

Found an error!
The following information may be useful in troubleshooting:
Traceback (most recent call last):

I see see error too, weird qtdragon doesn't get it (very similar code).
But (AXIS,hide) worked in Gmoccapy.

(AXIS,show) is available too, in this way you can hide/show different parts.

I think these special commands like (AXIS, xxx) should appear somewhere else in the docs than in the Axis page as they are relevant for some more GUIs.
Maybe in www.linuxcnc.org/docs/html/gcode/overview.html#gcode:messages ?
