1. I have not installed custom fonts.
2. Yes it started happening as a result on installing Mojave on my unsupported MacBook Pro.8,3
3. It is not limited to the Finder. I also see this issue when trying to access some menu apps like connecting to a wifi source.
4. While in Safe Mode the issue doesn’t not occur.
When booting up normally everything appears fine. The issue doesn't happen right away, but after several hours I may notice it which forces me to do a restart depending if I can simply work around it for the time being before I really need to do a restart to see what I am doing.
Any feedback would be much appreciated.
T.I.A.
