Original GitHub issue: https://github.com/amidaware/tacticalrmm/issues/1624

Server Info (please complete the following information):

OS: Ubuntu 20.04.4 LTS (Focal Fossa)
Browser: Google Chrome Version 116.0.5845.96 (Official Build) (64-bit) (running in openSUSE Linux)
RMM Version (as shown in top left of web UI): v0.16.4

Installation Method:

Standard
Docker

Agent Info (please complete the following information):

Agent version (as shown in the 'Summary' tab of the agent from web UI): N/A
Agent OS: N/A

Describe the bug
Viewing a script in Script Manager takes several seconds, consumes 100% CPU and the memory footprint balloons vary large.

To Reproduce
Steps to reproduce the behavior:

Open Google Chrome and perhaps other Chrome based browsers
Open Chrome's Task Manager
Go to Script Manager
Edit or view a script
Observe the Memory Footprint and CPU.
Observe how long it takes to view script.

Expected behavior
The script should appear immediately. Perform the same tasks in Firefox and it works.

Screenshots
Guest profile with no plugins viewing a simple script.

Additional context
Others have reported the same issue in Discord.

Observations

By "creating" I mean create the script, save it and then edit the script again to experience the hang or slowness.

The size of the script does not seem to matter.
Creating a new script does not have the problem.
Creating an empty script does not have the problem.
Creating a PowerShell script with Get-Item "C:\" causes the slowness.
Creating a Batch script with dir causes the slowness.
Creating a Python script with #!/usr/bin/env python3 causes the slowness.
Creating a shell script with #!/usr/bin/env bash causes the slowness.

This seems to be an issue only for Linux. I could not reproduce this on Windows or Mac. That could be why I didn't report it the first time I experienced the issue.

This is related to hardware acceleration as it pertains to the GPU. Check chrome://gpu/ or edge://gpu/ to see if hardware acceleration is enabled.

Ubuntu LTS 20.04 here. Chrome Version 116.0.5845.179 (Official Build) (64-bit).
After jumping to TRMM v0.16.4, there is no more delay (didn't tweak the GPU or hardware acceleration).
