It is definately not a kwin bug (not responsible for window content) and I doubt it is a KDE bug, but for that I have some questions: * Does it happen with other applications than Synaptics? * Does it only happen for applications using GTK+ (as Synaptics is a GTK+ application)? * Does it happen for applications not run as system user (as Synaptics is run as root and should use it's own font settings)? * Does changing the fonts settings for GTK+ applications in systemsettings change the behaviour? if this occurs for one particular combination of font/glyph/hinting it could be a fontconfig bug, otherwise (randomly hits glyphs across all fonts and hintings) it's the glyph cache on the server. for nvidia use "nvidia-settings -a GlyphCache=0" to turn it off, otherwise i don't know. you'll have to gg for your gpu/driver. notce that _not_ caching glyphs makes text rendering slow. *Yes, this happens for all applications *Nope. Happens for KDE applications as well *Exists for both root & non root users *Ive tried 20+ fonts with no effect. |
