Increase the sysctl option vm.max_map_count to prevent
crashes due to memory allocation limits in areas with

lots of geometry: Note that I am running at 4K so my setting of 2100000000 will be overkill for anyone running 1440p or 1080p
sudo nano /etc/sysctl.conf
enter the sysctl option vm.max_map_count

vm.max_map_count = 2100000000

sudo nano /etc/sysctl.d/20-max_map_count.conf
enter the sysctl option vm.max_map_count to prevent crashes due to memory allocation limits in areas with lots of geometry
vm.max_map_count = 2100000000

sudo nano /etc/systemd/system.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

sudo nano /etc/systemd/user.conf
delete # from the line "DefaultLimitNOFILE" and set value to
DefaultLimitNOFILE=2100000000

If the virtual memory set is not enough you can temporarily increase this value by entering in a terminal the command
sudo sysctl -w vm.max_map_count=2100000000

Output: vm.max_map_count = 2100000000
