This enables coordinate system scaling for high-DPI displays, which enforces correct proportions even on small 4k displays. The icons are scaled up without interpolation, which makes them crisp, but a bit pixelated. A new scalable icon set will solve this problem, but is not scope of this patch. Resolves #548, #1381, #1710, #1888 In addition, this patch enforces the KeePassXC icon theme for the KMessageBox close icon, since using the system theme produces very ugly icons on some Linux systems.

Works for me. Looks fine. Thank you! |

Icons still super-small on windows: 3000×2000 (267 PPI) respectively. |

This was merged into develop, are you using the 2.4.0 snapshot to test? https://snapshot.keepassxc.org |

Nice on HiDPI screen, but makes second screen that is FHD un-usable. Needs to be adjustable, best if automatic, when moving the displayed windows b/w monitors of different types. |
|
Version 2.3.4 still works perfectly well, both screens are fully usable for me, 2.4.0 doesn't have any option, that I can see to turn off this new "feature". |
|
I'm affected by this problem too. It looks like this is now discussed in #2808, so I suggest to continue over there. |

Description
This enables coordinate system scaling for high-DPI displays, which enforces correct proportions even on small 4k displays. The icons are scaled up without interpolation, which makes them crisp, but a bit pixelated. A new scalable icon set will solve this problem, but is not scope of this patch.
Resolves #548

Resolves #1710
Resolves #1888
As a small extra cookie, I snuck in enforcement of our icon set for the message box close icon (which has displayed a weird box on my KDE system ever since #2317 was merged).
Motivation and context
Icons were tiny, widgets had inhomogeneous proportions and windows were way too small as a result.
How has this been tested?
Tested on a 13.3" 4k Dell InfinityEdge display under Windows 10, works perfectly.
I also tested it in an Ubuntu 18.10 VM. It works in principle, but Gnome does not set all required properties. For Qt to pick up the correct scaling, DPI may need to be set manually using
xrandror KeePassXC needs to be started withIf the fonts are still slightly off, they can be corrected by also setting
QT_FONT_DPI=225. I don't think I can fix this any better. It is definitely working, though, Qt just may not pick up all settings automatically.Screenshots (if appropriate):
