Fresh Install of Ubuntu mate 24.04 LTS. After starting the Onboard keyboard, the "Onboard Keyboard icon indicator" will appear in the panel indicating that the program has started and currently running. Virtual Keyboard will appear but when I move the mouse cursor over to the Virtual Keyboard or the "Onboard Keyboard icon indicator", the whole program will disappear. No error message.
I tried to boot into USB "ISO Live Session", the same crash happens.
In the previous Ubuntu Mate 22.04 LTS, this was working fine.
I believe you're right! In an Ubuntu MATE 24.04 LTS ("Noble Numbat") VirtualBox VM, I activated the "On-Screen Keyboard" (available either in the "Ubuntu MATE Menu" -> "Universal Access" -> "Onboard" or by clicking om the accessibility icon in the task bar and by then sliding, to the right, the "slider" for the "On-Screen Keyboard" option). The on-screen keyboard then appeared on the screen but, when I mouse clicked on any key in that virtual keyboard, it disappeared. In my case, it did generate a ".crash" file named _usr_bin_onboard.1000.crash located in the /var/crash directory.
You may want to click on the "This bug affects 2 people. Does this bug affect you?" link in that Launchpad bug web page (to add yourself to the list of affected users by that bug) and you may also want to add a comment in that page to report your experience about this bug.
On a related note: a few minutes ago, in that same bug web page in Launchpad, I've clicked on the link to add myself as one of the affected people and that had the result of changing the bug status: "Status changed to 'Confirmed' because the bug affects multiple users."
