The 12.3 Front End so unresponsive?

Has anyone else noticed that the front end is slow to respond to editing or entering code? I have a recent laptop with lots of memory and processing speed, and an Nvidia graphics card, but when typing the front end is slow to respond.

Typing can be very slow if the cell you are typing into is very large. IĀ suppose it is because the Front End has to reformat the whole cell after every keystroke. If it becomes unbearable, you may type somewhere else and then copy-paste.

I am experiencing the same problem. When typing into a new cell there is a delay -- long enough that at first I thought my keyboard was an issue. Other applications did not have this problem, only Mathematica. I would close all applications, update the computer, do a Disk CleanUp, reboot and still had the same problem.

I am also finding that Mathematica will not move to the front when there are multiple applications open. The Mathematica window will appear when I click and hold the shortcut icon on the bottom of the screen, but will disappear on the click up / release. I have to minimize the other windows to get to and work on the Mathematica window...

Thank you for these comments. I wondered about my keyboard too, but I noticed that it's only Mathematica. I opened the task manger to watch my CPU load - not related, but I noticed periodic burst of high GPU load, just when the notebook window was really lagging. But I was just typing ...

I work on a big monitor connected to a laptop. The two screens work and different scales. When I drag a notebook from the laptop screen to the attached monitor, the text becomes huge during the transition, and sometimes I have to wiggle the notebook back and forth to get the text back to the appropriate size.

Have the same experience here, even in almost empty notebooks. Sometimes when I'm done typing I still have time to watch the frontend complete the typing. But its very irregular and not always so usually when it starts I restart Mathematica which sometimes solves it, but not always.
