[SOLVED] Album View like molasses when Cover Backdrop active.

[DRONE7]

Yes, should have mentioned that...just tried again to be 100% certain and no change.
Also using Firefox 123.0.1 on Linux.
8/4 art layout

Edit...Aha!  the accompanying default of Cover Blur at 5px seems to be the culprit...changed to 0px and now Library Album View is snappy again with Cover Backdrop and no Cover Blur.
