Description João Figueiredo 2024-08-01 00:26:13 UTC

SUMMARY
When updating to plasma 6.1.3, all icons suddenly became blurry. The attachments showcase it using the system tray, but it can be seen all throughout the system. I am using fractional scaling, but it still occurs under integer scaling and no scaling. It doesn't seem to be a breeze issue, I've tried other themes. Launching plasmashell with QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor improves it, but it's still not as sharp as it used to be. Text seems unaffected.

I'm wondering if this might be a Kirigami.Icon regression, or a Qt 6.8 regression.

Does the issue reproduce with icons in QML-based apps too, such as Discover, NeoChat, Elisa, or Filelight?

Tested Elisa and Filelight, both are affected

Thanks. Probably a Kirigami.Icon issue, then. Moving over there. I'll test this out on a 125% scaling FHD screen soon.

With current git master and Qt 6.7.2, cannot reproduce at 100% scale, 125% scale, 200% scale, or 225% scale.

For debugging purposes, can you still reproduce the issue in a new clean user account with no customization?
