Bug ID: 368843 Summary: kmail2 message view with qtwebengine hidpi is broken Product: kmail2 Version: Git (master) Platform: openSUSE RPMs OS: Linux Status: UNCONFIRMED Severity: grave Priority: NOR Component: UI Assignee: kdepim-b...@kde.org Reporter: br...@ioda-net.ch With hidpi 144 or more (I've 168 and 288 dpi screens) the display message viewport is completely broken. Seems kmail2 code doesn't apply this simple fix https://bugreports.qt.io/browse/QTBUG-54114 Mention High-DPI on WebEngine documentation, and recommend to set QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling) before creating Q*Application. THis is actually recommended for all applications (see http://doc.qt.io/qt-5/highdpi.html). For WebEngineView specifically, it makes sure that the default scaling factor of pages is reasonable. Reproducible: Always Steps to Reproduce: 1. open kmail2 with qtwebengine on high dpi screen 2. cry :-) 3. loose your eyes :-)) Actual Results: Wrong scale (dpi and scale factor) in message list So click on link is no more feasible, copy and paste is completely wrong etc. can't activate click to read pure html message and so on. Expected Results: Wrong on hipdi as well on normal 96dpi Screenshot coming -- You are receiving this mail because: You are watching all bug changes.
