Selecting 'Tickmarks' causes dashboard to hang in Safari - works fine in Chrome and FireFox

[juggledad]

macOS Mojave 10.14.6 Safari 14.0 12 Nov 04:58:23 - [info] Node-RED version: v1.1.3 12 Nov 04:58:23 - [info] Node.js version: v12.13.0 Dashboard version 2.23.4 node-red-contrib-ui-artless-gauge v0.1.48

How to reproduce 1) add node-red-contrib-ui-artless-gauge to a new flow 2) set the 'Tab' ad 'Group' to the default 3) Deploy and go to dashboard - the node will show up 4) close the dashboard window 5) click the "Tickmarks' option 6) deploy and go to the dashboard at this point (using Activity Monitor) Safari jumps to 100% cpu usage and after closing the dashboard window, the node-red editor window is blank and must be closed and opened back to the editor.

Thank you for reporting. As I don't have any mac device, the fix will not be quick one.

If you can do one more test for me I may have more clues for investigation.

What happens if newly added gauge has tick marks configured at first deploy.

[juggledad]

that causes it t hang.

However, I found something that may help. If I have an inject node send a numeric value to the gauge on deploy, it works fine. It only hangs when nothing is sent to the node and I go to the dashboard.

I have a similar problem with Safari on macOS an iOS. The radial gauge is working, but if i have one or more linear gauges Safari doesn't show the NodeRed UI. In Chrome it is working.

[juggledad]

@FreeTechNick uncheck the "Tickmarks' option and see if it works

[FreeTechNick]

@juggledad No change, not working in Safari and working in Chrome as before.

[hotNipi]

@juggledad can you confirm that radial layout works and issue is only with the linear layout

[juggledad]

@hotNipi - I can confirm it works with radial.

Hi @juggledad and @FreeTechNick
I found something with potential risk for safari, fixed it and released patch. Can you please update to 0.2.1 , try and give me feedback is there is any change.

[juggledad]

@hotNipi Yeah!!! that fixed it for me.

Oops, spoke too soon. While my test in the first post works, the original flow still fails and hangs Safari

[hotNipi]

Try to clear browser cahce

If you can, share the original flow (possible part of it) where you use artless gauge(s) for me to investigate per widget configuration if there can be something ...

[juggledad]

I just played again, clearng the cache and having 1 occurance and it works. If I add two more occurances it still hangs.

[FreeTechNick]

@hotNipi Here it is the same working with one and not with more.

Hi @juggledad and @FreeTechNick again Some more modifications made to catch the issue. I know it is a pain to deal with the thing which kills your browser but what can I do : ( New version available 0.2.2 Any feedback appreciated.

[FreeTechNick]

@hotNipi No change. Still the same situation.

[hotNipi]

Sad. I'm running out of ideas.

[FreeTechNick]

can we do any debugging

[hotNipi]

As far I know the safari tends to kill the debugging tools with browser window so for such issues there is only one way to debug. Turn off most and start to add functionality one by one until the issue reveals. I'd do this immediately if I had any ios device. Cant figure out is there some ways to do this kind of work with shared sources.

[hotNipi]

Hi @juggledad and @FreeTechNick again Would you please try again with v0.3.2 I may be found something... not sure but promising.

[FreeTechNick]

I just tested it with 0.3.3 but no Change in Safari (Mac) only one linear gauge is working and with more the UI is not working. In Chrome it is working without problems

[hotNipi]

Thanks for testing it. Sad there was no improvements.
