Suddenly, lately, I’m getting these black windows: “. . . [app] is not working.”/“You may choose to wait a short while for it to continue or force the application to quit entirely.” with buttons for Force Quit and Wait. Sometimes, it goes away spontaneously and I work without losing unsaved work. Sometimes, it goes away spontaneously, comes back, and goes away again. If I click a button, usually it’s Wait and then it’s okay. This has happened with LibreOffice, Firefox, and the Gnome app Files (probably a/k/a Nautilus). I don’t remember if it happened with any other app.
This used to be occasional and I’d Force Quit. Maybe I had clicked on an app’s button 20 times and then I’d get this. That made sense, and was helpful. But now I’m getting it when I alt-tab to an app window and maybe clicked in the app’s window once or not at all. And I’m getting it often. Rebooting, warm or cold, is not solving this.
Maybe it started after a recent F32 update, but I don’t know.
I’m getting slownesses, too. I’ll wake my computer but then logging in through my screensaver is often slow. Or I’ll close a Firefox tab and it closes so slowly that, after it closes, no other tab is self-selected for a bunch of seconds, maybe a minute, and I have to wait foor a tab to become the new default before I can do anything with any tab. I don’t know if that’s related to the Force Quit problem.
I speak words not fit for family radio and my computer, after a while, obeys, but, since the mic is off in hardware Setup, that’s not the cure.
What’s causing this? If it’s a bug and I should report it, which software has the bug?
