Public bug reported:
Filed by mark on behalf of low vision user Ken. Ken is able to read 56 point
type without magnification at normal reading distance and can barely read the
universal access "large text" from a distance of about 2.5 inches from a 26inch
monitor at 1360x768. So he really needs magnification and a lot more than the
2x default I used here for testing. We do not live in the same town so
providing additional details would be slow.
Turned on zoom from the universal access button on top panel.
Default settings were used including Zoom = 2.0, screen part = full
Several areas are corrupted. These zoom and scroll separately from the
rest of the screen and in a way that severely impairs use as portions
may not ever be visible. Portions of these subwindows cannot be used
because you have to move the mouse off them to be able see them so you
can either see or click but not both.
These areas are:
- The top panel
- The left panel (launcher) (intermittently)
- pull down menus, particularly the universal access pull down from the top
panel
Also, the zoom randomly every couple seconds. jumps to a different position
without the user's consent. This appeared to be because text was printed by a
program running in the terminal window (long apt-get install) but continued to
happen even when that window was minimized and even when that program stopped
printing.
These problems persisted with all the other zoom modes. One mode,
however, created new bugs. With "magnifier extends outside of screen",
you lose the ability to see the top and left panels at all; you can pan
over where they would be but they are not drawn. Can't open the
pulldown menu since there is no icon, so who knows how it would be
rendered.
These bugs made it very difficult to get screenshots, especially with
the defective screenshot program gnome-screenshot which ships with
system. Also, the bug-reporting program did not permitted attaching
additional screenshots once spectacle was installed.
Ubuntu 18.04, fresh install, only a few added packages (ham radio
related, chrome). Not using wayland, though a wayland session runs
concurrently with X11 even though no one has logged in with wayland.
Another problem in making the bug report is the irresponsible practice
of failing to identify the software being used. The accessability man
in circle menu does not have a heading to tell you what program is run
for the accessability menu or any of the functions thus invoked. Nor
does the settings. And there is no tooltip, popup, or about menu item
to convey this information to the user. And running a diff on ps
doesn't show any new processes started when zoom is turned on.
