Found by openQA: https://openqa.opensuse.org/tests/1106024#step/start_wayland_plasma5/21 The "Desktop Session: Plasma" label next to "Virtual Keyboard" in the bottom left is the same color as the background, so practically invisible. Switching back to PlasmaComponents 2.0 (like "Virtual Keyboard" already is) makes it appear properly again.
I have a patch to fix that: https://phabricator.kde.org/D25699 Would appreciate your review.
Git commit e4e1613b0fe741aa6330810560bedf71b25e0e4c by Filip Fila. Committed on 11/12/2019 at 12:50. Pushed by filipf into branch 'master'. [PC3 ToolButton] Have the label take into account complementary color schemes Summary: We've ported the SDDM theme to PC3 and now have black labels in PC3 ToolButtons (keyboard and session button). The SDDM theme uses a complementary color scheme, which is something the PC2 ToolButton respects and turns the labels white. Therefore I just copy pasted PC2's label color code to its PC3 counterpart. FIXED-IN: 5.66 Test Plan: ``` import QtQuick 2.13 import org.kde.plasma.components 3.0 as PlasmaComponents import org.kde.plasma.core 2.0 as PlasmaCore PlasmaCore.ColorScope { colorGroup: PlasmaCore.Theme.ComplementaryColorGroup Rectangle { height: 80 width: 100 color: "red" PlasmaComponents.ToolButton{ anchors.fill: parent text: "sup" } } } ``` The label was white instead of black.
