Comment 3 for bug 1798481

#2 Thanks for the comment. I'm accustomed to blinking following focus. The values I have in dconf are:
cursor-blink: true
cursor-blink-time: 1200
cursor-blink-timeout: 10000

I built vte 0.54.1 and ran the test app with debugging messages on as you described. There is a line referring to "Cursor blinking settings" which appears during launch:

Cursor blinking settings: blink=1 time=463 timeout=10

No new debug messages appear when I adjust cursor-blink settings in the dconf editor and save them. Relaunching the vte test app after saving new cursor-blink settings in the dconf editor does not change the "Cursor blinking settings" line at all, unfortunately.

I had adjusted the cursor-blink-time yesterday to something shorter to verify that THAT setting was being honored, and at the time it was - and presently that shorter blink time is reflected in the vte test app, gnome-terminal, xfce4-terminal, gedit and the pidgin instant messenger input pane.

Do gedit and pidgin have some relationship with vte? (I'm not very familiar with the GNOME ecosystem.)

I changed cursor-blink-time to 1205 and rebooted my system to see if that made any difference and the vte test app still reports "time=463" and all those GTK apps still have the cursor blinking fast. So it seems yesterday I at least had the capacity to affect a change to how fast the cursor blinks but now I've lost that capability. I'm not sure where to look next. Thanks!
