[BUG] Linux + Firefox: Right click breaks future left click/drag events

[lonelyteapot]

What is the bug?

After right clicking once, the map gets permanently stuck in a state where it cannot be dragged. On left click, instead of moving, it behaves as if the user was performing a pitch&zoom gesture.

The only fix I found is to reload the page.

How can we reproduce it?

• Visit the live demo in Firefox on a Desktop
• Move the map using the mouse
• Right click anywhere
• Try to move the map again

Do you have a potential solution?

No response

Platforms

Web (Firefox; X11; Linux x64)

Severity

Obtrusive: Prevents normal functioning but causes no errors in the console

Unfortunately, I'm unable to reproduce on my Windows (64-bit) machine running Firefox 118.0b9 beta. I can't test on Linux right now, but I find it unlikely that the behaviour will be much different between the same browser on different OSs. For the record, I also couldn't reproduce with Chrome 118.0.5993.11 dev.

Please ping for this to be reopened if you're sure the issue only affects Linux.

I've tested again on a clean installation of the same Firefox version (118.0b9).
The issue persists.

Here's a clip of moving the map holding left click:

And here is Troubleshooting Information from Firefox just in case: https://pastebin.com/UpQRhUzr

Unfortunately, I don't have any other desktop machines right now. This one is a pretty standard installation of Endeavour OS (Arch btw).

@lonelyteapot Thanks for adding a video, I can see a bit clearer what's going on now. The right click is being treated as the center of a two finger rotation, and the dragging left click as a finger.
Very strange, but not unexpected with the current state of the gesture system (see all the other gesture issues on Apple devices). Why can't there just be a standard way of doing things 😂.

How do you close the right-click context menu? I'm assuming a simple left click off of it?

I have an Ubuntu dual boot that I should be able to check tomorrow, but couldn't do it today.

Yes

Thanks!

I can reproduce this on RHEL8, using Firefox 102.15.0esr. No right-click issue with other browsers.

Indeed, I can also reproduce this on my Ubuntu distro with Firefox.

Could this issue be in Flutter, or even Firefox?

[JaffaKetchup]

I'm marking this as blocked, as I can't think how we should be doing anything differently here.

i can also confirm that i can reproduce this issue on arch linux + firefox. i do not see this issue on chrome. my guess is that this is a flutter+firefox issue? i cannot see how our gesture handling would cause that to happen. commenting so im subscribed and might eventually take a look at this.

[JaffaKetchup]

Someone should probably report this to Flutter. Or even Mozilla, if the difference between that and Chromium is unintended.
I'll try to do it soon if I remember, but someone else feel free to!

We're closing this for now, as this seems to be an external issue.
