Description Pierpaolo Valerio 2018-08-16 07:10:42 UTC

Yakuake uses the blur effect on the console background. While it looks just fine on my fullHD monitor, on my 4k one (set up with scaling=2) only the top-left quarter of the window background is blurred, while the rest is transparent but not blurred. Konsole works fine on the same setup.

Steps to Reproduce: Just set up scaling 2 and open a yakuake window.

Build Date & Platform: Yakuake 3.0.5 on Manjaro linux (using plasma 5.13.4 and frameworks 5.48.0)

This shows how the blur effect from desktop effects consistently only blurs a portion when the display is scaled.
