Description

Scrolling using my mouse wheel is dead slow on Firefox/Ubuntu for a few weeks now. It used to work fine before. Interestingly the markdown preview works as expected.

Reproduction Steps

  • open any editor, scroll with mouse wheel -> observe slow scrolling
  • open a markdown preview, scroll with mouse wheel -> regular scrolling
    slow-scrolling

OS and Theia version:

  • OS: Linux Mint 19.1 Cinnamon (based on Ubuntu 18.04)
  • Theia: 0.12.0-next.2186ccb7 (on gitpod.io)

Diagnostics:
none

It was fixed in latest Monaco. We have to review TypeFox/monaco-languageclient#178 and then follow https://github.com/eclipse-theia/theia/wiki/LSP-and-Monaco-integration#migration-guidelines.

@akosyakov Can we somehow support in getting this resolved? Or alternatively is there any workaround (patch, extra config) that we can apply to our Theia bundle?

Yes, someone should do what’s mentioned in my previous comment.

Confirmed on Windows 10 with Firefox, makes working quite hard.

Tested on Ubuntu 18.04.1 LTS and Firefox 68.0.1 (64-bit) against #7149
Looks like the issue will be fixed by upgrade of Monaco version:
