Description Giovanni Grieco 2018-10-06 19:58:54 UTC
Created attachment 1491175 [details]
This is a screenshot from Gnome Shell with settings app open and clicked on the clock to show the calendar.

Description of problem:
Zoom accessibility feature displays broken visual elements in the top-bar. Top-bar elements are rendered in half (only the top-half of the bar is visible) if the cursor is on top of the screen. Also tooltips and windows are not showing entirely, only portion of them.

This problem also affects GDM zoom feature.

Version-Release number of selected component (if applicable):
gnome-shell-3.30.0-9.fc29

How reproducible:
Always reproducible with gnome shell, gdm and Gnome Settings app. 

This problem does not affect other applications like firefox, rhythmbox and nautilus: these applications are rendered correctly.

Steps to Reproduce:
1. Activate zoom feature, wither from accessibility icon or via settings app
2. Move the cursor around and notice the broken elements

Actual results:
Windows, tooltips and other visual elements are not displayed correctly. It seems their rendering are limited on a rectangle near the cursor.

Expected results:
Windows, tooltips and other visual elements should be displayed correctly.

Additional info:
I tested with Fedora 28 Workstation, same setup, and the problem does not verify.

This message is a reminder that Fedora 29 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '29'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 29 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 Ben Cotton 2019-11-27 19:44:20 UTC
Fedora 29 changed to end-of-life (EOL) status on 2019-11-26. Fedora 29 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
