Package: gwenview Version: 4:18.04.0-1+b1 Severity: normal Dear Maintainer,
On high DPI monitors (1440p, 4K), where KDE configuration is set to upscale the interface in System Settings > Hardware > Display and Monitor > Scale Display > Scale - greater than 1x (othewise ui elements are too small), gwenview ui seems correct, but the images it displays are upscaled, making them blurry/with high pixel blocks (low resolution). I've uploaded a screenshot to https://jynus.com/side_by_side.png so you can understand what I am talking about. On another application, a-non perfectly crisp image would be a minor issue, but on an application made explicitly to visualize images this is a larger issue, impacting its main functionality (images are shown, but they look bad)- specially for photography visualization. To workaround the problem, one can do: unset QT_SCREEN_SCALE_FACTORS Before runing gwenview so the upscaling is cancelled for this application only and the images are shown with an appropiate resolution. I belive this to be the same issue as the one tracked upstream at: https://bugs.kde.org/show_bug.cgi?id=373178 -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-2-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gwenview depends on: ii kinit 5.54.0-1 ii kio 5.54.1-1 ii libc6 2.28-8 ii libcfitsio7 3.450-3 ii libexiv2-14 0.25-4 ii libgcc1 1:8.3.0-2 ii libjpeg62-turbo 1:1.5.2-2+b1 ii libkf5activities5 5.54.0-1 ii libkf5baloo5 5.54.0-1 ii libkf5completion5 5.54.0-1 ii libkf5configcore5 5.54.0-1 ii libkf5configgui5 5.54.0-1 ii libkf5configwidgets5 5.54.0-1 ii libkf5coreaddons5 5.54.0-1 ii libkf5filemetadata3 5.54.0-1 ii libkf5i18n5 5.54.0-1 ii libkf5iconthemes5 5.54.0-1 ii libkf5itemmodels5 5.54.0-1 ii libkf5itemviews5 5.54.0-1 ii libkf5jobwidgets5 5.54.0-1 ii libkf5kdcraw5 18.08.0-1 ii libkf5kiocore5 5.54.1-1 ii libkf5kiofilewidgets5 5.54.1-1 ii libkf5kiowidgets5 5.54.1-1 ii libkf5kipi32.0.0 4:17.08.3-1 ii libkf5notifications5 5.54.0-1 ii libkf5parts5 5.54.0-1 ii libkf5service-bin 5.54.0-1 ii libkf5service5 5.54.0-1 ii libkf5solid5 5.54.0-1 ii libkf5widgetsaddons5 5.54.0-1 ii libkf5xmlgui5 5.54.0-1 ii liblcms2-2 2.9-3 ii libphonon4qt5-4 4:4.10.2-1 ii libpng16-16 1.6.36-5 ii libqt5core5a 5.11.3+dfsg-5 ii libqt5dbus5 5.11.3+dfsg-5 ii libqt5gui5 5.11.3+dfsg-5 ii libqt5opengl5 5.11.3+dfsg-5 ii libqt5printsupport5 5.11.3+dfsg-5 ii libqt5svg5 5.11.3-2 ii libqt5widgets5 5.11.3+dfsg-5 ii libqt5x11extras5 5.11.3-2 ii libstdc++6 8.3.0-2 ii libx11-6 2:1.6.7-1 ii phonon4qt5 4:4.10.2-1 Versions of packages gwenview recommends: ii kamera 4:17.08.3-1 ii kio-extras 4:18.08.3-1 ii qt5-image-formats-plugins 5.11.3-2 gwenview suggests no packages. -- no debconf information
