(sorry for slightly late report)
I am happy to report that both planned under the hood improvements have
been implemented thanks to the grant:
1. Smarter Map Redraws (https://github.com/qgis/QGIS/pull/40960)
This is helping to avoid the annoying flicker when map in the map canvas is
zoomed or moved. It is especially noticeable with background maps. The work
has reduced the problem especially for raster layers. See the videos of
2. Tile Download Manager (https://github.com/qgis/QGIS/pull/40998)
This chunk of work is not going to be very visible to the users, but it
should make QGIS behave nicely with remote servers - until now it would be
common that QGIS would request raster/vector tiles, then abort the requests
while they were in progress when map got moved/zoomed, only to start those
requests again - this should be avoided now.
Many thanks to QGIS.org!
