lags and slow performance of cards, new trello,

[MH]

I would like to ask if there is any way to reduce lag and slow performance of cards in the new version of trello. The interface change has caused me huge slowdowns and lags when opening cards. There is no way to scroll smoothly through a card. It makes whole system nearly unusable.

@Jo Masson / @MH the Trello team has made several improvements that should reduce or eliminate the performance issues that you're seeing. Would you please reload Trello and let me know if you're now able to use it without issues? Thanks!

[Jo Masson]

Yeah it's back to normal! However I find the app much more fun to use so I'm gonna keep on using it. thanks for the follow up though.

Have these performance updates been rolled out to everybody? - the new UI looks like a massive upgrade - but it is painfully laggy for me. 

[Andrea Crawford]

Hi @marvc1  these updates have been rolled out to everyone, so I'm surprised that you're still experiencing lag. Could you share some info about what you're seeing to help us troubleshoot?

• What operating system, browser, and browser version are you using to access Trello?
• Have you tried disabling browser extensions to see if there is a change in performance?
• Can you describe some scenarios where you're seeing slowness? Is it when you open a card? when you are editing a card? navigating between boards? etc.
• Do you keep Trello open in multiple browser tabs at once? or just one?

Thanks for helping us debug this issue.

I use the latest Chrome on Windows. I tried Edge, and it was working fine. So I started looking at extensions, board power ups, and different boards. 

The lagging was with with the new menus, and scrolling the board, and hovering over cards. 

I turned on "Use graphics acceleration when available" in Chrome, and it has resolved the issue.

If I turn that off again in either Edge or Chrome, it's replicable.

So my underlying issue will be to do with CSS effects. It would be great if there was an option to turn these off. Trello is fantastic tool, the fancy effects are just noise.

The new layout is a great improvement I didn't know I needed.

On my system, due to the virtualization technology used, it is not possible to use hardware acceleration. It would be great if it would be possible to disable unnecessary graphical effects that slow things down.

@MH thanks for this info about virtualization tech!  This is a helpful clue.  We do take advantage of respecting an operating system level setting for "prefers reduced motion" to disable some animations.  We need to do an audit to ensure that is consistently done for all animations, though (will prioritize doing this).  Are you able to set prefers reduced motion?  From a different thread it looks like you might be using Linux?  And if you can set that does it help?

@marvc1  thanks for sharing about turning on "Use graphics acceleration when available" in Chrome resolving the issue.  That was a very helpful clue.  That setting is usually on by default so guessing you turned it off for a particular reason?  Are you able to leave that setting on by chance?  

Lastly, you asked about CSS animation/effects.  As mentioned to MH in reply just above, we do take advantage of respecting an operating system level setting for "prefers reduced motion" to disable some animations.  We need to do an audit to ensure that is consistently done for all animations, though (will prioritize doing this).  Are you able to set prefers reduced motion in Windows?

Hi everyone.

We are actively working on these issues (which is not an excuse, just sharing the latest updates with you).

We anticipate to gradually bring performance back to normal within the next two weeks.

[Victor Dronov]

@MH I apologize for this experience. We are actively working to resolve a number of known performance issues.

[Jo Masson]

Yeah I’m having the same issue! I’m using Trello as my CRM and it’s very annoying. Any news on when it’s gonna be resolved?

[MH]

Unfortunately, there is no improvement in system performance. Every attempt to scroll the card still results in a high CPU load. This is not normal. I am very sorry, but this will mean that I will have to give up on Trello in the near future. I have been using Trello since at least 2017, but such a terrible change I cannot accept.

[Jo Masson]

Yo! I downloaded the desktop app and it works flawlessly for now. Try that and let me know!

[MH]

Unfortunately, this is not the solution for me. There is no trello client for linux systems

[Jo Masson]

Maybe use a PC emulator (I know it sucks - I'm on mac and sometimes i need those to use certain apps ) - There are a bunch of pretty straight forward app out there that could helo you achieve what you need.
