I have a Mid 2011 iMac that is displaying weird graphics behaviour. Any guidance would be appreciated. This usually happens at the start of the work day and dissipates through the day.
Got a tip for us?

2011 iMac models were known / prone to developing GPU failures - and this very much looks like one. Classic symptoms.

Apple had an out-of-warranty video card replacement program for the issue, at least for AMD Radeon HD 6970M GPUs (Google for „HT203787“)

Sure. Here's some deets: 2.7 GHz Intel Core i5.... 16GB ram, AMD Radeon HD 6770M 512 MB OS 10.13.6 High Sierra.
Other than this annoying graphics issue the machine sings along. I'm a photographer shooting for commercial jobs, so I kind of need a properly functioning system.

You are going to have to replace the GPU as it is starting to fail. Next stop on this train will be a black screen.
Here is thread discussing upgrading GPU to newer compatible GPU.

This helps me with my decision to swap this machine for a modern Mac Mini as I have zero interest in fixing anything that is essentially outdated. I'll probably pull the 1TB SSD drive and recycle the rest the machine. I paid only $700 for it about 6 years ago, so I'm not overly concerned over the expense.
Big jump from Intel 2011 to M2 2023 Macs. Make sure your crucial software has updates compatible with macOS Sonoma before you pull the trigger. It’s not just the cost of a new Mac.
