Recently, after an
apt update / upgrade, it seems a delay was introduced during the greeter.
Most of the greeter / login loads, except the user background. Instead, a dark purple background appears with the dots grid. It is also unresponsive to input until ... after about 5 seconds, the user background loads, and any input typed during the delay appears (in the password field). I can then login as usual. But the delay is obviously annoying.
Not sure what is causing this. Any ideas?
