Subject: [PATCH 301/398] sd lok: ccu#1295 force async image swap
|
|
|
135360 |
|
|
|
135360 |
This helps ensure that images are swapped in when we actually
|
|
|
135360 |
render tiles. Previously we'd sometimes have placeholders
|
|
|
135360 |
instead of the image, which results in either an invalidate
|
|
|
135360 |
(+rerender of that tile) once the image is swapped in (for
|
|
|
135360 |
normal tiles) or a permanently missing image in the preview tiles.
