images.google.com - Scrolling using a tablet/pen combination fails

[ninthtale]

URL: https://images.google.com

Browser / Version: Firefox 116.0 Operating System: Windows 10 Tested Another Browser: Yes Chrome

Problem type: Something else Description: Scrolling using a tablet/pen combination Steps to Reproduce: So this isn't just an issue with images.google.com but youtube, as well. I haven't tested this on any other Wacom device, but I'm using a Wacom MobileStudio Pro 16 (first gen). On both sites, when you use the pan/scroll feature of the tablet pen, and try to just scroll down, it also simulates the holding of the left and right keys; in images this results in a somewhat chaotic passing through each image in the search results, and on YouTube it scrubs through the video.

This behavior does not occur in Chrome or Edge.

The problem is mitigated by changing the setting to just "Scroll," but is not entirely eliminated. Scrolling left and right (anywhere on the pages, to be clear) still has this same effect.

@ninthtale Thanks for the report. We are not able to reproduce the issue on Tablet PCs, running both Linux and Windows. @ksy36 Can you take a look , please?

Tested with:

Browser / Version: Firefox Release 117.0 (64-bit)/ Firefox Nightly 119.0a1 (2023-09-03) (64-bit) Operating System: Windows 10 PRO x64 Operating System: Ubuntu 22.4 LTS x64

I can reproduce this on a Wacom, trying to pan scroll up and down in the right panel (underneath the red cat image) makes it so the left area is scrolled as well and the image on the right gets changed very fast.

Can reproduce the issue on youtube as well. It does scrub the video, when pan scrolling through the videos list on the right:

I'll move this to needsdiagnosis. @softvision-raul-bucata wonder if you tried pan scrolling these side panels on your tablet PC? Or it might be Wacom-only issue

Quick update: I was only using my Wacom tablet PC before, but I'm trying it on my work computer with a Wacom Intuos small (model CTL-480) and the problem persists, again only in Firefox.

Another behavior I'm noticing is by changing it to just "Scroll..." instead of "Pan/Scroll":

Google images has two panes once you click on any given image; the left and right panes operate somewhat independently from each other with scrolling behavior.

In other browsers, the location of the cursor is detected automatically upon pressing this button in this mode with no issue.

In Firefox, which pane you're hovering over does not seem to be detected, and the scrolling does not behave as expected.

However, I'm also realizing there might be some extra nuance to this that I didn't notice before. I have been using this button by habit, as it's more or less universal. I don't remember it being the case before, but maybe I simply hadn't noticed, but Firefox is effectively already using a tablet-touch mode when a tablet is being used. That is to say, without pressing any buttons, simply click-dragging up and down with the pen produces the behavior I expected/desired upon pressing the scroll/pan button.

This is also true for YouTube.

If I had to guess (somewhat blindly at that), I might wonder if the default touch-style stylus scrolling behavior is somehow conflicting with the Wacom Tablet Properties programming? Like maybe it's trying to do both at once and creating weird behavior?

Second update.

I was testing what I learned on my work PC with the auto-pen behavior and the Tablet PC (Wacom MobileStudio), and it seems what I thought was a default tablet touch mode is actually connected to Windows Ink. When it is turned on in the Wacom settings, the tap-scroll behavior function works but then if the Pan/Scroll button is pressed it will run through the images/youtube timeline.

@ksy36 It seems to be a Wacom issue, as pan scrolling works for me.
