Description Nate Graham 2020-07-23 21:36:50 UTC
All KDE software built from git master as of an hour ago.

See attached screenshot. With a high DPI scale factor (tested both 200% and 250%), Plasma notification popups suffer from the following visual glitches:
- The plasmoidheader does not touch the left and right edges of the window
- The corners are sharp and pixelated rather than smooth, rounded, and anti-aliased.

Attaching a photo from my phone because Spectacle is incapable of taking screenshots on Wayland with proper resolution (Bug 409762), which masks the issue.
Comment 2 Nate Graham 2020-07-23 21:55:49 UTC
The corner glitchiness is masked if the notification appears over a light colored background, but will be visible if it appears over a darker one.
Comment 3 Nicolas Fella 2020-07-23 23:45:42 UTC
Can confirm the corner issue, but the header works fine for me on 2x

My corners look better too, so I can't confirm either
Comment 6 Nate Graham 2020-07-24 03:11:19 UTC
That's on Wayland with a high DPI screen and ≥200% scaling?
Comment 7 Nicolas Fella 2020-07-24 09:11:43 UTC
yes, Wayland and 2x scaling. I do have a non-scaled one too, but the notification is on the scaled one
Comment 8 Nate Graham 2020-07-25 00:04:42 UTC
Fixed by clearing the plasma SVG cache after changing the scale factor.

Marking as a duplicate of Bug 424615, and will probably be fixed with https://invent.kde.org/frameworks/plasma-framework/-/merge_requests/50.
