I'm using Tableau Desktop (public edition) 2026.1.1 to edit multiple workbooks on my Win 11 workstation and the program is suddenly extremely laggy. Just selecting dashboard objects causes a multi-second delay where a blue circle spins and "Not Responding" appears in the status bar alongside the dashboard name at the top of the screen.
Is anyone else experiencing this issue? I've edited these workbooks repeatedly without issue over the past few weeks, so I'm wondering if this might relate to the service outage 2 weeks ago that resulted in Error Code: 9F4C5638.
I'd appreciate any input!

I’m also seeing similar behavior in 2026.1.1, where Tableau suddenly becomes slow and shows “Not Responding” for a few seconds. I haven’t seen anything official about a major issue, but it does feel more common than in previous versions.
In my case, the lag tends to appear after working for a long time or when the workbook gets heavier. Restarting Tableau or even rebooting Windows has helped, and cleaning up unused sheets or switching the dashboard size settings has also made things a bit smoother.
I’m also curious to hear if others are experiencing the same slowdown in this version.
