1523783 - about:performance content rows hidden behind header with 65.0 build update

Status: RESOLVED DUPLICATE of bug 1523654

(Toolkit :: Performance Monitoring, defect)

Description

[­]

Attachment: about_preformance.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

Simply open about:performance page...

FYI, the issue is noticed using latest available FF public release (65.0 32 bit).

Actual results:

The 1st element/row/line in the table is partially hidden behind the table header.
Modifying zoom scale or changing window size has no effect.

If that helps, with the previous version of FF Task Manager, this issue was not present (without Memory column added):
"Easier performance management: The revamped Task Manager page found at about:performance now reports memory usage for tabs and add-ons."

Expected results:

No overlapping, I guess ;-)

In case you manually remove from the page CSS the below parameter, that issue is fixed:
#dispatch-thead { position: fixed; }
To avoid getting some empty space, at least one of the below should also be disabled:
#dispatch-tbody { display: block; }
#dispatch-tbody { margin-top: 2em; }

WOW thanks for your super fast response :-)

Well, as I best remember (unfortunately I did not keep any previous ver. screenshots) this problem was not present in the previous build (64 - localized Greek version).

And since I've been checking FF Task Manager constantly, I have noticed that this issue appeared the moment the new feature of Memory monitoring was embedded (current: 65.0 - localized Greek version)!

I am at your disposal if you need some further info...

Thank you,
