Linux desktop client: Moving mouse over server icons is very laggy
Running Ubuntu 21.04, AMD Radeon RX550, Ryzen 5 3600, 16 gig RAM
Using the latest official desktop client.
Steps to reproduce: Move the mouse pointer up and down over the server list.
Noted behaviour: The animations are very laggy and there's very high CPU load in multiple cores/threads.
I'm not sure but I don't think it was like this before the most recent update.

This is still a problem, I don't mean to be a jerk to discord staff but this is pretty disappointing

So firstly; this has nothing to do with linux. It seems to be a problem on windows platform too, so no need to try pull the "you don't care about linux" card.
Hovering over multiple unique servers does increse the delay, but it is annoying to try to find the reason when everything is minified.
A quick performance capture shows that there is a task that takes ~56ms (on my system) the frame I do a hover on a server icon. When the task is complete then another task is immediately fired due to more mouse movements in the time it took the first event to finish.
It gets noticable enough (on my system) after hovering over 20 servers. Grouping servers together seems to have no positive effect on the issue.

So firstly; this makes this even more embarassing and sad than I thought. I assumed it could only be a Linux thing because otherwise an issue this obvious would get noticed and fixed immediately. I guess I'm giving discord way too much credit.
and secondly I'm really frustrated with the quality of service after the many problems I've dealt with that actually were specific to the linux version, so I'm voicing that.

this is really sad, 2 months of this ridiculous extremely obvious bug and it's still broken. this is like if the start menu was broken on windows 11 or something. can't believe it honestly.

This bug seems to have been fixed a few days ago (for windows atleast). I am unsure about linux, but considering the fact it was a shared bug it should be fixed for linux too.

Definitely hasn't been fixed on my system. Theoretically I should be in contact with the Discord team, though they haven't responded to me in nearly a month, so it's not looking good.

I cancelled my nitro anyway. Not giving money to discord again

Seems to be fixed on my system too (linux)

still broken lol

I am having a similar issue as well but in the mean time I am just using Windows until this is fixed and then ill had back to linux

Still broken for me too.
The web version doesn't have this issue. The desktop app does.
If you look into developer tools -> performance it is caused by 'Composite Layers'1 -
Still have this issue.
I noticed something: for me lags appear only on chromium applications (google chrome and the discord application itself, for example).
Noticing this, I decided to check firefox, and found that there were no problems with animations there. I dare to suggest that this issue is associated with chromium applications.2 -
Yep, the same behaviour here.
Works fine in firefox. Lags in chrome based apps.1 -
still a problem on arch

still a problem on debian

I thought this had to do with my Chromium-based Vivaldi, previously Windows and now Linux Mint, the problem is present in Chromium web version as well (doesn't happen on Firefox yet, but I don't use that browser). When I e-mailed the support team, they said they couldn't guarantee it to work unless it's their recommended browser, Chrome itself. It works fine on Vivaldi 3.7, but not post-3.8 versions.
Apparently, it doesn't have to do with any of that, but some kind of Chromium 90.x engine update might've caused it? Discord's desktop application is a built-in browser too, after all (try Ctrl+Shift+I). It is extremely annoying and unusable because of this weird bug.
EDIT: I've moved to Linux and use Firefox now. I cannot be more thankful that an alternative web engine exists to Chromium.

It's still broken after 4 months, even after I spoke to someone on the discord team, even after more than one person submitted bug reports, after it's been confirmed it happens on more systems than just linux, this is absolutely unacceptable.

i've been having the same issue for months (arch linux 5.16.5, AMD ryzen 7 3700u, radeon vega 10)

Looks like version 0.0.17 of the Linux desktop client just released, but the performance issue is still present on my system.
To make things worse, version 0.0.15 (the last version without the bug) doesn't work any more - it crashes on launch. I sure hope there's another workaround other than just using Discord through a non-Chromium browser.

Same here, just updated and it's still laggy

I've done some more research, and it turns out that a solution for this has existed for a long time, and it was even added to the Arch Wiki back in October last year (but somehow I and many others missed it).
To solve the issue on my system, all I need to do is launch discord with the flag --enable-gpu-rasterization.
So launching discord from the terminal would look like:discord --enable-gpu-rasterization
Here's the link to the info on the Arch Wiki:
https://wiki.archlinux.org/title/Discord#Lagging_when_scrolling_through_your_guilds
They have a few more command-line arguments listed to try if the one I used doesn't work for you.There's some more info on the Manjaro forums:
https://forum.manjaro.org/t/discord-server-panel-lagging/84400If anyone who sees this can spread the word about this fix, please do. It helped me and the people I know, so I'm sure it could help many other people.
I have observed this flag also working on Windows, so it appears to be a global fix.If you use Discord in a chromium-based browser, you can launch the browser with this flag too (since this a chromium flag), and it will fix the performance of Discord in the browser.

That workaround solved this issue, thanks
