When invoking the Yakuake with a panel positioned at the top of the screen, yakuake flickers in the part covering the panel. It seems like the rendering of Yakuake and the panel is conflicting. Things that help: moving the panel to the bottom (yakuake doesn't overlap anymore) or changing the panel to "autohide"/"windows go below". X11+QEMU virgl on a macOS might be highly relevant here.

Same here running running on bare metal and not inside a vm. There are currently two workarounds for me, both with its own set of drawbacks: 1. "Configure Yakuake -> Windows": Below "Size and Animation" uncheck "Ask the window manager to perform the animation", but I get some other rendering issues (incomplete rendering of yakuake until mouse over and similar) 2. Use wayland. Sounds like a good solution but I need to use proprietary software (webex) for work which still only works partially with wayland.

Should add, the two workarounds that Siddhartha mentioned work for me as well.
Adding the x11-only keyword
Facing the same issue even on the real hardware as well: Operating System: NixOS 25.11 KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 Kernel Version: 6.12.51 (64-bit) Graphics Platform: X11 Processors: 32 × AMD RYZEN AI MAX+ 395 w/ Radeon 8060S Memory: 128 GiB of RAM (94.1 GiB usable) Graphics Processor: Radeon 8060S Graphics Manufacturer: Framework Product Name: Desktop (AMD Ryzen AI Max 300 Series) System Version: A6
