Touchpad scrolling doesn't work

[alexey-kozlenkov]

• VSCode Version: 1.5.3
• OS Version: Windows 10
• Laptop: Asus n56-vz, I'm using Asus Smart Gesture drivers for touchpad.

Suddenly touchpad scrolling stopped working.

Steps to Reproduce:

1. Add a lot of code yo see a scroll bar.
2. Try to scroll with 2-finger gesture - doesn't work;

Not sure about the reason of this behavior.
I've been using VSCode for several hours, than I turned my laptop into a sleep mode.
After waking it up back, VSCode no more responses on a touchpad scrolling (with 2 fingers).

I tried to reboot the system, no effect.
I also tried to reinstall VSCode, but it seems like I haven't achieved complete removing (cause, for example, all my extensions were safe), so it didn't help too.

Have anyone also faced with such an issue or maybe there are some tips to do in order to solve this problem?

Adding important to raise awarness and seems like a regression

[alexey-kozlenkov]

Actually, there is a kinda cure for this problem.
The complete uninstall + deleting registry records for VS Code and then installing it back helped me.

It doesn't look like a solution, but helps to get back to work.
This problem happened twice with me near the date I've posted this issue and since then VS Code works fine.

What registry records are there left over when uninstalling? I couldn't find any. Uninstalling and reinstalling did not solve the issue for me.

[alexey-kozlenkov]

@nathanielwarner Not sure where to find them manually in registry, I had used external tool (Uninstall Tool) to perform complete uninstalling (including registry records).

AFAIK we had no changes in the scroll handling logic, but we did update to a newer electron version (that includes Chromium 52). In another thread @jhasse mentioned noticing issues with Chrome that went away with Chrome 54

It would be interesting to find out if Chrome 52 also suffers from this issue. We have the exact same scrolling code in the editor https://microsoft.github.io/monaco-editor/ so if anyone would like to try it and report here the findings, I would be thankful.

There are plenty of touchpads issues on Chromium: https://bugs.chromium.org/p/chromium/issues/list?can=2&q=touchpad

Are we hitting a known issue for them?

I can confirm this happens to me as well, XPS 15 with precision touchpad. Please let me know if there's anything I can do to help track this down. Thanks.

[hchris28]

I also am experiencing this problem on an XPS 15, am happy to help track it down.

[alexdima]

In #13612, -- #13612 (comment) -- we have received confirmation that this was an issue with Chromium 52 that got fixed already in Chromium 54. We are now sitting on Electron 1.3.8 that is built on Chromium 52 and I am sorry that until we update, there is no workaround we can do on our side.

fyi @kieferrm @egamma @bpasero IMHO we should try moving quickly to Chromium 54 given all these trackpad issues. Also see #13612

[bpasero]

We cannot until Electron has updated to Chrome 54 which they only just started..

[dgiagio]

I'm wondering why this doesn't happen with Atom? Doesn't it use the same Electron version as VS Code?

[bpasero]

@dgiagio try Atom Beta to get the same Electron.

[dgiagio]

I'm using Atom 1.12.0, and according to this https://github.com/atom/atom/releases/tag/v1.12.0 it uses Electron 1.3.6 and Chrome 52. No problems with it so far.

[bpasero]

@dgiagio just wondering if our latest insider build changes anything for you. It now uses Chrome 53 instead of 52.
You can give our preview releases a try from: http://code.visualstudio.com/Download#insiders

The preview (1.7.1) fixed the problem for me on my Asus Zenbook.

[hchris28]

The preview (1.7.1) has not fixed the problem for me on my Dell XPS 15.

[michyprima]

The 1.8.0 preview still has the bug on my XPS 15.

[dgiagio]

1.7.1, 1.7.2 and 1.8.0 all still have the bug on XPS 15 with precision touchpad.

[michyprima]

If I can add something, scrolling is so fucked up on Chrome 55 I switched to Edge... I guess this will take time to get sorted. 👎

[hchris28]

I can confirm also that 1.8.0 still has the bug on my XPS 15.

[hchris28]

1.8.1 checking in, scrolling is still not working well.

[alexey-kozlenkov]

UPD

I've just figured out some magic.
If I run VSCode as an administrator, then scrolling does not work.
If I run VSCode just as it is, scrolling does work.

I have a Windows 10 Home Edition, for now version is: 10.0.14393 - build 14393

Hope it will help.

Happened with me again today.
Last VSCode update was several days ago, but everything was fine right before the update till now.

Scrolling extremely choppy and essentially unusable on version 1.81 with Dell XPS 15.

[alexdima]

Something I do on my Surface Book is to "restore" and then maximize the VS Code window. Somehow that makes it that two finger scrolling works smooth for me.

[hchris28]

I have found that the restore/maximize trick works on my XPS 15 as well, but it doesn't "stick" and may need to be done periodically.

[rcdmk]

The restore/maximize doesn't work for my ASUS X555U.

I have another trick that does work as long as I keep focus on the VS code window:

1. Tap with tree fingers, so Search/Cortana pannel shows up to the left of screen
2. Swipe with two fingers over the VS code window and notice that the document does scroll

I'm on version 1.9.0 on Windows 10 with all drivers updated. I've noticed this issue on 1.7 that was when I bought this notebook.

[Timvrakas]

Still an issue on 1.11.0 on my XPS 15.
Looks to be isolated to "Precision" Touchpads (used in both XPS 15 and MS Surface)
Switching to windowed mode and back to full screen fixes the issue for a bit.

[pendar747]

@Timvrakas I also confirm the same problem on my XPS 15 (Thanks for the temporary solution though)

[bpasero]

Todays VS Code insider build comes with Electron 1.6.x, would be interesting to hear if this update solves this issue for anyone: http://code.visualstudio.com/Download#insiders

[hchris28]

XPS 15 checking in again, scrolling is still choppy on version 1.11.1

[bpasero]

@hchris28 our insiders release is version 1.12.x

[hchris28]

Apologies.

[michyprima]

@bpasero 1.12 scrolling is still choppy on my XPS 15

[bpasero]

Any improvement or no change at all?

[michyprima]

not sure if there was an improvement but if there was we are talking about something nearly unnoticeable

[Timvrakas]

1.12.0 has no improvement here

No improvement in the latest insider build. Still have to reside the window every now and then to get around it.

Edit: My version:

[alexdima]

From reading through all the comments, I believe we should merge this issue and #13612.

Let's continue tracking in #13612, as that issue has the same number of upvotes, but more comments and more participants. I have also put together a wiki page that collects a summary of known workarounds to the scrolling problem at https://github.com/Microsoft/vscode/wiki/Known-issues
