Created attachment 156703 [details] Faint blue desktop wallpaper (its more prominent than it looks via spectacle) on which is the dolphin terminal panel showing a terminal window behind with `cd /home/user` and the terminal's dimension SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Open dolphin. (Super + E) 2. Open terminal panel (F4) OBSERVED RESULT The terminal panel seems to be showing a different terminal behind it with a glitchy transparency bug with its dimensions in the center and the glitch keeps showing both terminals. The glitch being the prompts appearing and then a clear terminal and then prompts reappearing again within a very short time, giving it a non uniform blinking effect. EXPECTED RESULT Normal terminal panel on dolphin with the prompt. SOFTWARE/OS VERSIONS Windows: - macOS: - Linux/KDE Plasma: Arch Linux 6.1.13-1-lts 5.27.1 (available in About System) KDE Plasma Version: 5.27.1 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Graphics Platform: Wayland Prompt: oh-my-zsh This bug does not happen with a standalone konsole window (with or without tabs). Just inside dolphin. The interactive part of the terminal is glitchy(rapid blinking), shows the prompt but it seems its being cleared instantly and displayed again. And there's another prompt behind it with a same sized terminal with the command and all the characters: `$/home/user/^J clear^J` and also shows its dimensions in a box in the center of the terminal. I can see the command prompt behind the interactive command prompt as the glitch blinking occurs, hence I'm sure there's two terminals. Behind both of these terminals is the desktop or whatever window is behind dolphin. Before updating to 5.27 it was normal, just opened up a terminal panel in the bottom part of dolphin. I disabled oh-my-zsh to go back to bash terminal, to no avail. It still glitches.
I reproduce this issue. * It is related to at least 20% background transparency on Wayland. * If disabling the background transparency, this issue is hidden or "no" issue. * If you use Xorg, but it does not show this issue, because the background transparency is always disabled or does not work on Xorg.

The update to dolphin 23.04.0 version fixed it.
