Whenever Photoshop has an issue a black box or outline appears around the splash screen. The software worked fine yesterday (v 22.4), but today it was extremely slow. The black box appeared around the splash screen. I updated to the newest version 22.4.1, but it remained slow. I went back to an older version, but it remained slow. I went online and saw that presets could cause Photoshop to load slowly. I removed Photoshop and re-installed v 22.4.1 without keeping preferences. Now it's loading better, but with the same presets it worked fine yesterday. My question is, why does photoshop allow presets when eventually and randomly the software runs slowly with them? The presets made my work so much easier and quicker. And, again, the software ran fine with the same presets using version 22.4 until today.
