Bug: Line number in code snippets doesn't stay on the left side when scrolling about bob HOT 11 OPEN

I scrolled with both the scroll bar and mouse wheel in all videos to show that with the scroll bar it can't be reproduced on any of them, including Firefox. What I didn't notice is that in the latter two videos I use the scroll bar first unlike the first one 😅

With chrome I start using the scroll wheel 10 seconds in. In safari 5 seconds in.

I'll try with the troubleshoot mode later today, and also update the Firefox version from the bug report to the current one

@Manueljlin I can no longer reproduce this issue. Could you please try again to see if you still have it?

from bob.

Well, this is weird.
When I'm not recording the screen, I can't reproduce it anymore with the external computer mouse, and only just slightly with the trackpad. The moment I do start recording though, it appears again.

Here's more detailed information:

KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.93.0
Qt Version: 5.15.2
Kernel Version: 5.17.3-1-default (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-10510U CPU @ 1.80GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics

Firefox: 99.0.1 (64-bit)

IIRC, I could reproduce it on a windows machine at school too, which might be easier to grab info from than to fight all of the opensuse downstream patches, xorg, kwin, nvidia stuff

Just remembered about this one. More info:

• Can reproduce with macOS 12.6 on an M1 Mini with a regular mouse + Shift and with the mouse's horizontal scroll wheel click thing (Logitech M720). Not exclusive to Linux, but that's not really surprising.

• Only happens with Firefox (in this case 105.0.1), not on Chrome or Safari.

I'll try on an M1 iMac + Magic Trackpad tomorrow and try to add more details for touchpads since I don't have the laptop from the previous comment anymore.

Closing in favor of #976.

I /think/ that's a different bug that just happens to also be for the line indicator

@Manueljlin Would you be able to share a full-screen video of the steps to reproduce this issue?

from bob.

Ok, here's a few more videos, this time macOS Monterey on M1 Mini. As for the steps, just scroll with a mouse while holding shift to move horizontally.

It only happens with Firefox, it seems. Upstream issue? :D

from bob.

Thank you so much for those videos. I noticed that in the Chrome/Safari videos you scroll using the scrollbar, was that intended?

It only happens with Firefox, it seems.

Could you please try again with Troubleshoot Mode (Help > Troubleshoot Mode)?

PS: I was able to reproduce a tiny artifact in Firefox 109.0a1 on Mac OS (Intel) when horizontally scrolling using Shift + mouse scroll:
