SUMMARY
Last working commit: d46864e0ade1f0edee7a6bc4b9f6a219baea79aa

Having a dock with absolute size 48px should show perfectly scaled 48x icons on the tasks applet. In latte-dock git, probably after ba502fa5951f9c5688d0ff6db06a25883cca5d7d, the icon size is not actually 48x (maybe 47x?) and the icon is blurry in result.

STEPS TO REPRODUCE
1. Dock with absolute size 48x, padding shouldn't matter, but I use 15%


OBSERVED RESULT
Blurry icons

EXPECTED RESULT
Icons look sharp just like in the last working commit (d46864e0ade1f0edee7a6bc4b9f6a219baea79aa)

SOFTWARE/OS VERSIONS
Linux: 5.10.12
KDE Plasma Version: 5.20.80
KDE Frameworks Version: 5.78
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Went back to commit d46864e0ade1f0edee7a6bc4b9f6a219baea79aa and it's fine. 
Tested 8ae3b4ecfb08c4c90fef3445aa1b1863b951644d and it's broken. It probably broke before that commit, but I didn't try compiling every commit in between.

On d46864e0ade1f0edee7a6bc4b9f6a219baea79aa setting the dock size to 47x or 46x (or 49x) still results in a midly-sharp icon. On latest git it's definitely way way blurrier.

Comment 2 Michail Vourlakos 2021-02-03 06:33:43 UTC

it comes from Items shadows. If you disable them they will look sharp. I will try to track it down.

Comment 3 Michail Vourlakos 2021-02-03 17:39:54 UTC

please try again, it should be fixed now. The should look crispy when the tasks an not hovered and when a task is fully zoomed through the parabolic effect.

Well, now they're not blurry, but it's definitely still not quite there: https://i.imgur.com/8R15adr.png

That icon definitely shouldn't look like that. Went back to d46864e0ade1f0edee7a6bc4b9f6a219baea79aa and it looks fine. 

Well. Might be worth another bug report since now it's not blur, it's... jaggy?

Comment 5 Michail Vourlakos 2021-02-03 18:58:33 UTC

yeah open it...
and we can forward it to Plasma afterwards. Latte is now using PlasmaCore.IconItems in roundToIconSize:false state so Latte can not fix this any more... 

Personally I can not do any better.

It might be on latte to be fair. The icons look *okay*, but if you hover over them then the icon looks bad and goes all jaggy and artifact-y (Parabolic effect issue?). I'll open the bug report with more details and a video.
