21.02.27 win64 hanging on large files

Shotcut hangs for minutes at a time.

Removing 21.02.27, and installing 20.04.12 win64 and behavior doesn’t happen anymore. Feels like a regression.

For some people, anything version 20.10 or newer is significantly more laggy, but we do not know why. For others, based on reports, only version 20.11 or 21.01 were significantly more laggy but most recent version 21.02 resolved it.

Or, to quote the proverbial parochial school teacher:

“It’s a mystery.”
