I just installed TDE on a new-to-me system running debian stable (buster).
All the initial system installation was done from a live CD, and it installed KDE. That installed version of KDE works as well as KDE ever works these days. In particular, though, the screen looks fine (1920x1200) and everything works as expected.
In the newly-installed TDE, though, the desktop flickers wildly and the desktop is simply unusable: input is lost during the flickers, so most keyboard/mouse input is not even seen by the desktop.
Where should I look to try to eliminate all the flickering so that I can get a usable TDE?
More info:
The background doesn't flicker at all. What is flickering are the panel and the default icons on the desktop, many times a second.
If I succeed in bringing up the TDE menu (which, if I click enough times, eventually does appear when I succeed in timing a click at a moment when the desktop is accepting input), then the flickering stops for as long as the menu is visible.
Really hoping for some helpful suggestions. I really, really, really, don't want to give up and use KDE5.
