Created attachment 150181 [details] Dolphin terminal panel warning message SUMMARY *** Following the upgrade to Plasma 5.25 the Terminal panel in Dolphin no longer displays the background color transparency although it has been set in the current profile and effective in Konsole window. *** STEPS TO REPRODUCE 1. Konsole > Settings > Edit Current Profile... > Appearance > Edit > Background color transparency: 50% 2. Dolphin > F4 OBSERVED RESULT Dolphin's terminal panel has no background color transparency, and if you right click in terminal panel, and select "Edit Current Profile..." and then "Appearance", an odd warning message appears as shown in the screenshot attached. EXPECTED RESULT Dolphin's terminal panel should have the same settings as in a regular Konsole window. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Having the same issue, and also with Konsole itself. The transparency setting is not saved. Konsole version 22.08.1 KDE version 5.25.5 on Arch Linux
(In reply to axel.wikstrom from comment #1) > Having the same issue, and also with Konsole itself. The transparency setting is not saved. Konsole transparency problem might be different. I don't have it with version 22.08.0 in KDE neon 5.25.5. Indeed I'm beginning to suspect that Dolphin developers might have decided to apply Dolphin-specific appearance settings to all panels, including the terminal panel, instead of applying Konsole's appearance settings inside Dolphin window.
Iirc this issue has been present since KDE was able to display transparent background for konsole, not just since recent versions of KDE. BTW the German wording for error message is "Konsole wurde gestartet bevor die Desktop-Effekte aktiviert waren. Sie müssen Konsole neu starten, damit der Hintergrund transparent wird." ("Konsole was started before desktop effects became effective. You need to restart konsole to make background become transparent.") ... which is strange because konsole is showing transparent background totally fine. If dolphin developers should have decided on separate settings for this then why does it have same settings / appearance window as konsole has.
I don't have this problem any longer. No, it wasn't fixed. What has changed is that I've begun using Darkly application style (https://github.com/Bali10050/Darkly), which provides a transparency setting for side panel, which apparently restores terminal panel transparency, as well, among any other features that I wish were included in Dolphin by default.
