Package: gnome-shell
Version: 41.1-1
Severity: normal
Tags: upstream

Dear Maintainer,

Problem occurs at the Show Applications page.
If the mouse moved over the slideSidePages at the left or the right of
the page with application icons, it hangs about 15 to 30 seconds,
before the arrow and a row of icons of the next page are shown.

This also occurs at the left slideSidePage of the first Applications page,
where
no arrow and icons will be showed,
and at the right slideSidePage of the last Applications page, which also
remains black.
Also switching to next-page with icons is very slow.

Problem is caused by updateFadeForNavigation, which requests fading,
which apparently is too heavy for the graphics card i915, causing switching to
software rendering.

A solution could be to bypass updateFadeForNavigation if animation is disabled. No functionality is lost, mouse-movement and page-switching is very fast then.

Normally I use dual monitor above each other with dash at the left side (dash-
to-dock)

In that case you always have to pass the slideSide Page to click on an
application-icon.

Suggested, working patch:
