Bug ID: 464342
Summary: Album art is rendered at a noticeably lower resolution
than originals
Classification: Applications
Product: Elisa
Version: 22.12.1
Platform: OpenSUSE
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR

Artwork in Party Mode compared to the original image in my music directory.
Note that the songs do NOT have any embedded artwork, so Elisa must be pulling
from this 1024x1024 image.
SUMMARY
***
In Party Mode, album art is rendered at a noticeably lower resolution than the
original image which it is pulling from. This is an issue no matter what scale
factor Plasma is being run at.
In addition to this, art in the album list view is rendered at an even lower
resolution, which is especially noticeable because you can compare it to the
smaller image in the top bar, which is sharper. I assume the covers of the
album list view is rendered based on the expected resolution of a screen
running Plasma at 1x scaling (maybe for the sake of speed?); this issue in
particular is almost unnoticeable at 1x scaling (but I have a high DPI screen,
so I use 1.5x. I also tested 2x, and it's still a problem).
***
STEPS TO REPRODUCE
1. Have a music library with somewhat high resolution covers.
2. Have Elisa import that library.
3. Observe Elisa's album view, or open Party Mode while an album is playing.
OBSERVED RESULT
Artworks are noticeably more blurry than they would be in an alternative music
app.
EXPECTED RESULT
Artworks should appear sharp, assuming the source image is high resolution.
