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

diamondburned commented 6 months ago

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.

carterprince commented 6 months ago

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":

Here's a video of this effect:

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.
