Interface stutters on main window scroll

[phpony]

So I've resized all images to my size with this command:

cd /home/user/.cache/com.github.tkashkin.gamehub/graphics
find . -iname "*.jpg" -print0 | xargs -I{} -0 mogrify  -resize 392x220^ -gravity center -extent 392x220 {}

And now scrolling is not stuttering, but covers are still not "instantly" shown. There's still a delay of 1-2 sec after them appear on screen.

Probably should try to replace this to always true and try to compile my very own build:

GameHub/src/ui/views/GamesView/list/GamesList.vala

Line 106 in 9327885

row.icon_is_visible = !is_before_viewport && !is_after_viewport;

Wrong file but yep. Changing this:

GameHub/src/ui/views/GamesView/grid/GamesGrid.vala

Line 95 in 9327885

card.image_is_visible = !is_before_viewport && !is_after_viewport;

To this:

card.image_is_visible =true;

Fixes everything. No stutters, fast scrolling. Probably a bit of memory eaten and first start is slow, but overall that's what I've wanted.

For my opinion, there's another "cache" folder required with properly resized images for current grid dimensions in it. Changing display settings should wipe this folder and re-create new thumbnails. And so there should be no icon_is_visible control at all and no image processing on each start/load/scroll event. Just simple "load from cache => draw all at once".

Combining code patch with approach:

find ~/.cache/com.github.tkashkin.gamehub/graphics/games/ -iwholename "*/images/*.jpg"  -print0 | xargs -I{} -0 mogrify  -resize 392x220^ -gravity center -extent 392x220 {}

made GameHub blazing fast. Fast start, smooth scroll. So probably caching of resized images and drawing all cards at once is a good idea.
