Description Lili Huang 2020-08-21 08:19:40 UTC

Description of problem:

OSK does not disappear sometimes by clicking [v] key (screenkeyboard3.MOV).
Even if the [v] key works, not whole OSK disappears, part of OSK still
remains on the screen (screenkeyboard2.JPG , screenkeyboard1.MOV ).

Customer is using a DMC USB Touch display and a Dell SmartCard Reader Keyboard. This issue happens no matter the physical keyboard attached or not.

Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux 8.1 (Ootpa) 8.1 (Ootpa)
Booted kernel:  4.18.0-147.el8.x86_64

gnome-desktop3-3.32.2-1.el8.x86_64                          Mon Sep  1 11:56:13 2014

- There is a similar bug on gnome upstream. And seems the fix is already available.

Yes. 2 bugs raised from the same customer. But I do not think it is the same issue.
In 1833787 customer complained he can not disable the OSK, but in this bug customer complained after click the [v] key, sometimes OSK does not disappear and even if the OSK disappear, a part of the keyboard still remains on the screen. The image and video attached to the case should provide you a better understanding.
And to some extent if the OSK can be disabled completely, this could be a workaround of this bug, because customer will not have to face this issue until he enable the OSK.

On our subsystem team meeting we approved this bug for 8.4 RPL.

Comment 26 Michael Boisvert 2021-01-14 20:24:08 UTC

I thoroughly tested gnome-shell-3.32.2-27.el8.x86_64.rpm to look for any issues with the OSK. I did not find any usability issues like those outlined in this bug. I used a touchscreen machine running latest RHEL 8.4.0 and tested both Wayland sessions and X11 sessions. 

Lili, could you give the related package to your customer and have them test for posterity?
