SUMMARY Issue introduced in Plasma 6. When the panel is set to Auto Hide, it's slow to pop up as you bring the mouse cursor to it. In Plasma 5 it would appear instantly the moment the pointer touched the edge of the screen, now it appears several milliseconds late sometimes an entire second. STEPS TO REPRODUCE Set default panel visibility to Auto-Hide, exit edit mode, move the cursor on and off the screen edge. OBSERVED RESULT The panel isn't immediately shown when the mouse pointer touches it, the cursor must be held on the edge for a random amount of time sometimes up to one second. EXPECTED RESULT This didn't happen in Plasma 5 and is a noticeable limitation when trying to operate quickly. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.9.0-1-MANJARO (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 570 Series
This was an intentional change; now the panel respects the delay setting that applies to all other screen edge effects, whereas previously it did not. If you don't like it, you're welcome to turn it off at System Settings > Mouse & Touchpad > Screen Edges > Activation Delay > set it to 0
