So I have a strange problem wtih Qt applications displaying broken pixmaps :
Theme and fonts are OK but some rendered images look badly aliased like that splash screen or the checkboxes buttons.
If I display maps in QGis they are bordeline unreadable.
Kde & GTK apps have no problem, only pure qt apps.
I have tried making a new config with qt5ct unsuccessfully.
If I launch those apps as root, the proble disappears.
Any idea on this ?
