Slow GUI and preview. aep causing BUG attached
I'm having this problem since the first release of AE 2020 (still bad in 17.0.5). The comp preview in attached "issue.aep" file is ridicilously slow. Every action requiring redrawing UI takes a lot of time and strongly loads CPU - impossible to work. "Hardware Accelerate ... Panels" option doesn't do any change. This project has many Shape Layers with Trim Paths and Fill Colors animation but works FINE and pretty fast on my machine in previous versions of AE (2019 for example).
My system: Windows 10.0.18363 Pro, Gigabyte Z390 M Gaming, i7-9700K, 32 Gb DDR4 3466 Mhz Dual-channel, Samsung SSD 860 Evo, Palit RTX 2070 Super.
