Upgraded from 5.3.0 -> 6.0.0 or 6.1.0 and centering not working and I am seeing rendering artifacts

[CoreyBalfour]

I an developing textual app and I recently upgraded from 5.3.0 to 6.1.0 and menu buttons that where centered are not centered any more. I am also getting rendering artifacts when I jump from screen to a modal dialog with transparency and hit ESC to go back.

I also tried 6.0.0 and same thing. I uninstalled and when back to 5.3.0 same code works cleanly.

I am running Ubuntu 24.04.

Anyone else seeing these issues?

6.1.0

5.3.0

I do use rich and override the rendering. I believe this is the root cause. I like the buttons centered, with keyboard highlighted only text background, and mouse over only change text color.

It looks like I fixed it I was originally using Align to center the text of buttons. Removed this and let the CSS handle this and it is fixed.

I will leave this here for information for other people.
