To Zoom Support Team,

I'm writing on behalf of my entire development team to report a critical and widespread performance issue we consistently experience when using Zoom's screen sharing feature concurrently with PHPStorm (an IDE by JetBrains). This problem significantly impacts our collective productivity and renders our development environment almost unusable during Zoom calls.

The Problem: Excessive CPU Usage and System Lag

When any member of our team is in a Zoom meeting and/or shares their entire screen, their system's CPU usage spikes dramatically. 

Specific Symptoms:

• Extreme Sluggishness in PHPStorm: The IDE becomes incredibly unresponsive. Simple actions like right-clicking to open a context menu can take 2-5 seconds, terminal commands execute with significant delay, and scrolling or typing within the code editor experiences severe lag.

• Overall System Slowdown: Beyond PHPStorm, the entire system feels sluggish, impacting other applications and general user experience for our developers.

• Consistent with Screen Sharing: This issue is directly tied to active screen sharing in Zoom. The moment a team member stops sharing their screen, PHPStorm's performance immediately returns to normal, and the high KernelTask CPU usage drops.

• Reproducible Across the Team: This is not an isolated incident. It consistently happens every time any team member shares their screen via Zoom while PHPStorm is open.

Our Team's Setup:

• Zoom Version: 6.4.12(64384)

• PHPStorm Version: 25.1.3

• Operating System: Windows 11

What We've Already Tried:

Our team has collectively attempted various troubleshooting steps, including:

• We've already escalated this to the official JetBrains + PHPStorm support team, and while they tried to help, their efforts were unsuccessful.

• Updating both Zoom and PHPStorm to the latest versions.

• Disabling plugins in PHPStorm.

• Resetting PHPStorm's settings.

• Adjusting Zoom's screen sharing preferences (e.g., enabling/disabling "Optimize for video clip").

None of these actions have resolved the issue for any team member.

Our Request:

This problem has also been documented by other users in the JetBrains YouTrack system as WI-81625, indicating that it might be a broader compatibility or interaction issue between Zoom's screen sharing mechanism and JetBrains IDEs.

Given that the problem immediately resolves when screen sharing is stopped in Zoom, it strongly suggests an interaction issue on Zoom's side with how it handles screen rendering or resource allocation when other demanding applications like PHPStorm are open.

Could you please investigate this issue from your end? It would be highly beneficial if your team could collaborate with JetBrains to find a definitive solution. This is a significant pain point for our developers who rely on both Zoom for communication and PHPStorm for coding.

Thank you for your time and assistance.

Hi Zoom community,

Could anyone suggest how to retrieve the duration of participants' webcam usage during a meeting? I’ve checked the Zoom API and dashboard but couldn’t find a way to access this data. Are there any alternative methods to obtain this information?

Thanks in advance!

I am looking to create an automated process (without having to use Zapier) where:

1. User receives an email to sign-up for a meeting.

2. User clicks on the CTA, which brings them to a landing page.

3. User signs up for meeting and hits submit, which brings them to a Zoom link.

4. User can then add meeting to their calendar, whether it is Google, Apple or Outlook.

Is there an easy way to set this up to make it low friction for the user and ensure an easy addition to their calendar?

Does anyone know if SMS for Zoom Phone Australia is unlimited texting or know the rate per text for AUS to AUS texting? Support keeps directing me to the international PBX rate page, but these are US to international I am pretty sure. This is a really good article https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0057987 on setting it up and limitations, but doesn't cover costs, if any, for Australia SMS. Any help would be appreciated!

Yes I know the alternative host needs to be in your same organization- and they are. im creating zoom rooms with alternative hosts that are a part of the same plan (we're all under a university) and some accounts zoom recognizes and zoom doesnt recognize other accounts. i know for a fact the emails that aren't working have been attached to a zoom account, so im not sure what the problem could be. is there any service i could use to manually appeal this, and get those zoom accounts registered? or is there no way? 

Why does my phone keep ringing in my headphones after I've answered?  No, there's not another call coming in.
It also continues to ring (in my headphones) if the caller drops the call before someone answers. 

Is there a setting to fix that?  If so, where?
