Bug ID: 406821
Summary: Dark UI color theme breaks default LightTheme
Product: frameworks-syntax-highlighting
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: theme
Assignee: kwrite-bugs-n...@kde.org
Reporter: kosse...@kde.org
Target Milestone: ---
SUMMARY
When using a dark UI color theme, with the default syntax highligting theme for
LightTheme those text regions which would be rendered using "Normal" textstyle
appear invisible against bright backgrounds.
STEPS TO REPRODUCE
1. Use Plasma, switch to dark color theme "Breeze Dark"
2. In Dolphin, enable preview of "Text Files" (needs KA 19.04)
3. Navigate to folder with text files, e.g. a dir with C++ sources
4. Enable "Preview" for folder, also trigger tooltips & info docker
OBSERVED RESULT
Rendered text misses out large parts of text to render.
EXPECTED RESULT
All text is properly rendered in some sane colors against the bright
background.
Additionally strange is that
QColor(highlightingTheme.textColor(KSyntaxHighlighting::Theme::Normal)) is
always QColor(ARGB 1, 0.121569, 0.109804, 0.105882). Matching the "text-color"
: "#1f1c1b" entry in default.theme.
Is there potentially a chance that instead of applying the "Normal" style for
such text regions, that the regions stay unformatted in the QTextDocument, and
thus Qt's rendering falls back to UI colors?
