In a new proposal, Microsoft has shared a solution to improve
Chromium’s touchpad-based scrolling. Microsoft wants to bring
Windows 10’s touch-initiated fling animation to fix the
slow movements when scrolling using two-fingers touchpad
The bug post
‘Fling curve on Windows should match Edge and other native
apps’ was filed by a user in 2016 and it has been recently
assigned to a Microsoft engineer. According to the bug post,
scrolling with touchpad’s two figures gesture is slow and flick
scroll gestures end almost immediately rather than inertial as
In a work-in-progress commit,
Microsoft says adding support for Win specific touch-initiated
fling animation could improve this behaviour. The commit hasn’t
been merged or reviewed yet.
According to the commit, this change will enable Chromium on
Windows to have a touch fling inertia that behaves more like
Edge and other native apps.
“Note that this implementation does not modify the curve
depending on the scroller’s size, something that may be
desired. User feedback will be used to determine the importance
of bringing that behavior to Chromium,” the commit reads.
In another commit,
Microsoft has shared the following technical details:
For fling and inertial scroll, the animation used by
EdgeHTML matches Windows and Microsoft design. This differs
from the animation built into Chromium by default. This CL will
add an option to use Microsoft fling animation curve for
touch-initiated flings rather than current default fling
One thing to note is that this fling curve is the same for
subscrollers vs root scrollers which is different than what
EdgeHTML had. We’re planning on running some user studies to
see if that’s an important thing to bring over or not.
