Erratic Behaviour When Selecting Large Amounts of Outlined Text
When I select large amounts of outlined copy - 200+ words - all of a sudden my screen display is very erratic (see attached images - these are all shot from the same file it flickers like that until I deselect the copy).
This has not happened in the past (this is something I have been doing on a regular basis for almost eight years now).
The text is all outlined. The document size is 38x58 inches. It happens with or without layers (the document has 3 layers and the art is on the bottom layer).
It does not happen on smaller amounts of copy (I don't know where exactly the breaking point is in terms of character count).
This is happening on files that I had performed the exact same functions on almost a year ago - literally the same files with minor text updates.
I am running an iMac:
Retina 5K, 27-inch late 2015
macOS - Catalina 10.15.7
24 Gigs 1867 MHz DDR3 RAM
AMD Radeon R9 M380 2 GB video
I have the latest version of Illustrator I believe - 25.1 - there are no upgrades that I see in my account.
This was not happening earlier in January. Just started this week (I don't do this every day so I can't be much more exact in terms of date, sorry).
I don't have issues in any other programs, so I don believe it is a hardware fail.
Sorry! One more important detail. It happens when I am selecting the text with the direct select tool and does not happen when I use the selection tool.
Here is the original file and some additional screen caps.
