Pure White Screen Background Reveals Flickering and Slow FreePBX Performance

Hi everyone,

Whitescreen is helpful to check for any display issues while troubleshooting my FreePBX installation, and pure white background screen clearly revealed a flickering problem on the web interface.

Aside from this, I’m also experiencing very slow registration with my phones (Yealink T46G, T30P, and T31P). When attempting to register, the process is stuck on “Registering” and “Registering Failed” for about 10-15 minutes before it finally completes.

Additionally, the server startup is taking an unusually long time. Every time I reboot, it takes around 10-15 minutes for the firewall to enable and for FreePBX to become fully operational.

I’m running FreePBX on a Proxmox VM with CPU set to host, 8192MB of RAM, and 2 sockets with 2 cores. Could the flickering issue or the delays in registration and startup be related to my VM setup or resource allocation?

Any help or suggestions would be greatly appreciated!
