Ghostly scrolldown in Browsers

[rethus]

Up from today there is an annoying issue in chrome-browsers.
If I open some pages, thy are scroll down the screen at their own in a ghostly manner.
I’ve tried it in Brave and Vivaldi

See this video, what happend if I refresh a Page (e.g. this Forum-Page here).

Ghostly Scrolling

BTW: Yesterday there was a bigger upgrade available. I’ve done this update.

First I thought, it might be a sticked key or broken mouse-hardware… so I’ve unplugged them.
But the issue remain.

As I use a laptop (keyboard and mouse are untouched in last days) I want to be sure that it’s not an hardware issue of the build-in keyboard and touchpad… so I’ve started “screenkey” where I also activate “mouse-monitoring”.
So no keypress or mouse-move are recognized.

BTW: It make no difference if I start the browser in general or incognito-mode

What might the error be?
As I don’t have this scroll-down behavior in other applications (I’ve tried kate, libre-writer, thunderbird, etc.) I think it might be an chrome-engine issue?!?

What do you think about this?

I’ve looked into journalctl -b -e -f and found many many entries like this:

Ah… ok, that is not in any dependency to the issue.
I’ve found that this was caused of my Screen-Recorder Application which runs in wine.
If I stop it, and refresh the browser… and ghostly stuff scrolling starts again, no logs are created in the Journal.

So question remains… what does happens here?

Hi @rethus,

Since you mentioned it works on correctly in some apps, and others not it looks like, to me at least, it is a GTK issue, since all/most apps you mentioned working is Qt. The reason I say most is because you mentioned Thunderbird and I don’t think it’s Qt.

So I’d recommend checking that. I do not know what the settings are or is named, but I think that’s where the answer lay, at least.

Possibly more:

[rethus]

Ok, your suggestion might point in the right direction. Checked it with firefox now, same result (ghostly scrolling).

What other GTK-Based application can I check for this bug?
And how to fix it?

Your linked page give me no Idea what the reason might be and how I may fix it. The posting is about a user who tells that his touchpad is to senstive. But I don’t touch any key or touchpad at all.

[Mirdarthos]

I also have no idea, sorry.

Thinking look into Gnome/GTK’s mouse/pointer settings/sensitivity. That’s all I can think of…

[rethus]

Got it.
It was ocra - the screen-reader implementation.
Lucky me, I found this redit-post.

Deactivating and restarting kde solved it.
