Keyboard keys stop working at random STM32CubeIDE Linux

I use STM32CubeIDE on Linux Ubuntu (and to a lesser extent on MacOS and Windows, but I don't recall having a problem on the last 2 operating systems). About once or twice a day, at random, several of the keys such as <backspace> and <enter> and <delete> stop working. All the alphabetical and number keys work as normal. If I switch to a different application all the keys are working, but when I switch back to Cube the problem continues.

I solve the problem by saving my work, shutting and relaunching Cube. Is this a bug in the application?

I've noticed this on Ubuntu also.  It seems to occur for me after generating code from the CubeMX view.  Restarting STM32CubeIDE resolves the issue, but it is quite annoying.

exactly me too.
I met very often while configuration tunings.

 

select lines and "Edit-Copy" then "Edit-Paste" by mouse operation,
after doing this likely solved for my cases.

it is still bother but easier than restart IDE for me.

I have the same problem. My solution is to open the Preferences menu (maybe any other popup window works) and close it by "Apply and Close". I don't do any changes on the Preferences.

I'm still experiencing a similar problem on the latest version (6.17.0) on Debian sid with Cinnamon. Though in my case the keyboard stops working entirely. I can't enter any text and keybinds like CTRL+S don't work either. It's coupled with very slow startup times of the program. Strangely it only manifests on my laptop and not on my desktop PC with the same OS and desktop environment.

That sounds like a CubeMX version ?

Is only your CubeMX affected, or also CubeIDE - if so, what version?

as in, for all apps - not just Cube-related ?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

I came from a search and someone failed to see this is about CubeIDE. How silly. This problem indeed only affects CubeMX, not CubeIDE.
