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

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.

@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.
