New update: Now the dialog takes about 45s to appear. I did not manually upgrade my system, and I haven't rebooted since my last update. The only difference, AFAICT, is that the system is up for more than a day, and I have been connected at times to a VPN that makes more printers available. It looks like the time the dialog takes to appear is 4-5s per available printer... Below is what appears in syslog. The messages that appeared only once in what I pasted yesterday now appear as many times as I have printers (14).
I also just noticed that while I am waiting for the print dialog to appear, I cannot launch any app, be it using a keyboard shortcut such as ctrl+alt+t (for Terminal), or using the dock, or using the applications browser. Once the print dialog appears, all the apps I attempted to launch during that time open at once. 2025-09-09T11:16:37.055289-06:00 tadzim5 org.gnome.Papers.desktop[822]: libEGL warning: failed to get
