I started building an ETL job in Form 2023.0 that only reads in about 250 PDF files containing 1-3 pages where I need to extract some text. I've recently upgraded to 2023.1 and the issue still persists.

I've noticed after working on the job for a few hours the FME Form UI will randomly start to flicker as if my mouse button was stuck down and was spamming clicks every second. It doesn't trigger a click event and it only happens within FME. If you attempt to work around the issue it rapidly continues to get worse until the screen completely stops updating.

The only solution I have found once this starts is to save your work and restart FME.

I've attempted to attach a video of the issue.

In the video, I only zoom the view once despite it looking like I'm scrolling in and out really fast and I'm only clicking on each transformer or pathway once as well.
