1883277 - Scrolling to the end of the "Marker Table" has the rows snappy-jagged (not aligned, overlapping text)

Status: RESOLVED DUPLICATE of bug 1726431

(Core :: Layout: Text and Fonts, defect)

Description

[Mayank Bansal]

Go to https://share.firefox.dev/3P4w9G8

Go to the "Marker Chart" tab
Scroll to hte very bottom

AR:

1. The rows cut-off some text
2. If you pinch-zoom, the text jiggles a lot as if the snapping is going haywire (or some perspective thingy has gone wrong) . The text/rows/table at the top of this "marker chart" view is drawn correct. So it seems like the longer you scroll to the bottom, some perspective/snapping thing goes wrong.

Can repro on a build from Jan2021, so not a new regression.

I see something similar too.

I believe this is due to the fact that our "window" mechanism uses a very high container, and this might lead to rounding errors.

It's not clear to me which component it could go. I'll start with Font handling folks.

Correction:
(In reply to Mayank Bansal from comment #0)

Go to https://share.firefox.dev/3P4w9G8

Go to the "Marker Chart" tab\

=> Unless I'm mistaken, this is the "Marker Table" tab.

This looks like an example of what's described in bug 1726431.
