BBBv2.4, Upgrade to PC Chrome v114.0.5735.91 will cause the whiteboard to fail to draw !?

[MT88 HM]

Hi Fred and other developers:

We just found a new issue that we upgrade current Chrome v113 to latest v114 will cause the whiteboard to fail to draw on it.(No matter what component we use to draw on it.)

Can you help clarify this problem and how to solve it?
We currently still run based on BBBv2.4 platform, So any quick fix is the best for us.
Thanks.

Best regards,

mt88hm

We're now developing on 2.7 and supporting 2.6 as the official release.  Is it an option for you to upgrade to 2.6?

Regards,... Fred

Hi Fred:

1. Due some reason about human resources, we may need some time for porting from our custom project from v2.4->v2.6.
2. We haven't found any related discussion for this new issue. Is there any clue or solution that can be solved in short time?

Thx.

Best regards,

We can see that 2.5 draws on the whiteboard with Chrome 114.  BigBlueButton 2.6 with tldraw works fine as well (as we would expect).

Unfortunately not.  We (the core developers) have not done any work on 2.4 in many months.  Our focus is on supporting 2.6 and moving towards 2.7.

Instead of using 2.4, which is EOL, may find more support in moving towards 2.6, and you could try reaching out to companies that provide commercial support to help accelerate the process.

OK, Thanks for your quickly reply and provide some useful information, and we can take for reference to find our best solution.

Thanks.

There is an issue submitted in Github: https://github.com/bigbluebutton/bigbluebutton/issues/18066

I can confirm the problem in 2.5.17 in Chrome and Brave on MacOS. Obviously on the presentation-overlay component, the area that accepts mouse events is limited. The area changes (in its size and position) depending on the size of the BBB window. Moreover, when you zoom into the presentation, the area that does not accept events enlarges. Consequently, if you zoom in around 200% using the mouse wheel, you will stuck, with all mouse operation disabled; you need to zoom out using the toolbar button before re-activating the operation.

So far I don't find any bug or error in the source code. I would bet it's a bug in Chromium-related browsers...but you never know.

[Hiroshi Suga]

BTW my 2.5.17 server was upgraded three days ago from 2.4.0. I also upgraded Ubuntu to 20.04. It is thus possible that the problem comes the drastic upgrading.

Hi Hiroshi,
We met the same issue no matter on 2.4 or 2.5.

Thx for your PR.

Hi Fred,

The issue is still on v2.5.

Hi MT88HM,

See PRs that I proposed right now:

https://github.com/bigbluebutton/bigbluebutton/pull/18084

https://github.com/bigbluebutton/bigbluebutton/pull/18085

They may offer a quick workaround until Chromium fixes a possible bug. 

I would recommend you, however, to upgrade at least to 2.5.17 so that you can receive the fix and support. I am pretty sure 2.4 would never receive them (even the source code has been removed already). 

[MT88 HM]

Hi Hiroshi,

Thx for your PRs support, before to see your PR's hotfix we ourselves have already found another work around solution:
const viewBox = `rect(${viewBoxX} ${viewBoxY} ${viewBoxWidth} ${viewBoxHeight})`;

clipPath={viewBox}
We test it on our basedv2.4 project, it works for us.

But we have missed your performance consideration and hot fix.
We may try your clipPath removable solution and apply it again.

Any other comment?

Thx for your sharing and supporting.

Thx.

Best regards,

Hi MT88HM,

yes, I have confirmed that your solution works as well. 

In the meanwhile I have submitted another solution:

https://github.com/bigbluebutton/bigbluebutton/pull/18086

Let's see what the devs decide. Whatever they decide, I am just fine as I can start the class from tomorrow;-)

Hi,

I am using 2.4.9. I can't do the upgrade option right now. Can anyone explain to me step by step how you solved this problem? I've reviewed these 2 issues, but I didn't quite understand where and what to do.

https://github.com/bigbluebutton/bigbluebutton/pull/18084

https://github.com/bigbluebutton/bigbluebutton/pull/18085

Thanks for your help in advance.
