[Qgis-user] Disable map update in Layout Editor?

[Prud'homme Jérémie]

Hi,

What you are maybe looking for is this option that was available in QGIS
2.18 and 3.4 :
https://download.qgis.org/qgisdata/QGIS-Documentation-2.18/live/html/en/docs/user_manual/print_composer/composer_items/composer_map.html
Render mode : rectangle, cache, render.

Maybe it has been removed with the more powerful computer arising ?

Best Regards,
Jérémie.
