Scrolling is laggy when mouse is hovering over messages, smooth when hovering over blank area

Title -- this also happens for the channel list. Is there an easy fix for this?

Interesting. Are you scrolling using a touchpad? Do you know if your application is rendering via Cairo (software) or OpenGL (hardware)? You should be able to check that via Ctrl + Shift + I, in the Global menu.

Yes, I am scrolling with a touchpad.

It mainly happens in fullscreen when in a channel with a lot of embeds/images.

Here's a screenshot of the first section under "Global":

This kind of effect also occurs in GNOME Files? So maybe it's an upstream issue. Or maybe my computer is just slow.

Hm, that is interesting.
I do not know if it is an upstream issue, but in any case, scrolling like this with mouse hovering should not lag like this, even on relatively under-powered hardware.
If I can get my hands on a slower device than the one I currently use, I will try it, but no guarantees.

If I have to guess, it's the hover background transition. I'll see if I can experiment with it.

Yeah, the lag was unbearable for me on a low end system...

Does turning on the Reduce Animation accessibility option help with this?

I updated my Arch system and the performance problems went away! That's weird. Cannot reproduce anymore.

excuse the dumb question...what program is that? i cannot find those settings in dissent...

I consider this a solved issue, might've been a bug with the renderer. I think we can close this issue.
