**System Information** Operating system: Gentoo Linux Graphics card: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] **Blender Version** Broken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen) 2.92 Worked: (newest version of Blender that worked as expected) N/A **Short description of error** For some reason, displaying a UIList with many collection properties next to a bool property somewhere in the same property tab causes a huge amount of lag. A bool property which is part of another property group seems to be another workaround to this issue. I'm developing an add-on which requires the display of large collection properties for construction management of 3D buildings in Blender, which is how I came across this bug. **Exact steps for others to reproduce the error** Based on the default startup or an attached .blend file (as simple as possible). See attached script, or attached blend file on how to reproduce. The lag seems proportional to the the number of properties in the collection property. {F10033442} {F10033443}

Run script, go to scene properties tab and scroll. Then comment out L19 and try again, lag disappears. {F10033442} {F10033443}
