@donq Yep, that was it! The problem was caused by an extension: Text to Speech (TTS) by mornicolhkher. I uninstalled it and everything is back to normal. Thanks, @donq and everyone else who replied, for your help!

@burnout426 Yes, I did, and also, when uninstalling, I was directed to a survey where I logged the bug for the developer's eyes only.

@burnout426 Thanks for doing the test on your computer and replying. Sounds like this may be issue specific to my Opera installation. I am at a loss, though, as to what may be causing it. My Opera version is the same as yours now (76.0.4017.123), and the problem is still there.

One interesting detail is that I can select and drag static text on any internal Opera settings page, such as, for instance, the About page, but not on regular websites.

Any suggestions for what I can do to further diagnose or resolve this issue?

Starting about a week ago, Opera has been having trouble keeping its window position from one session to the next. Before that, it always opened in the same place where I always keep it--flush with the left and top edges of the screen. Now, it opens shifted about 20 pixels or so to the right from the left edge (and still flush with the top edge, no problem there). Adjusting the window, closing and then reopening it produces the same error in horizontal positioning every time. This only happens when I place the window within 20 pixels of the left edge. If placed anywhere else, the position is remembered correctly. It looks as if some setting is not allowing the window to remain too close to the left edge of the screen. This is only happening with Opera. Other browsers (Google, Edge, Firefox) have no trouble keeping their position. Any idea what's going on with this?
