Created attachment 163793 [details] rules SUMMARY I have some window rules set up set up for Firefox picture-in-picture as shown in the screenshot, as a workaround for Firefox not being able to set those properties on Wayland. However, when set to "apply initially", they only they only apply the first time you open picture-in-picture, not subsequent times. The properties will apply again once Firefox is restarted, but only once. This issue does not happen if you set the properties to "force". STEPS TO REPRODUCE 1. Set up window rules like in the screenshot (window title would differ depending in language) 2. Open picture-in-picture 3. Close picture-in-picture 4. Open picture-in-picture again OBSERVED RESULT The properties only applied to the first picture-in-picture window EXPECTED RESULT The properties applies to all matching windows SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20231110 KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 Kernel Version: 6.6.1-1-default (64-bit) Graphics Platform: Wayland Processors: 8 × AMD Ryzen 7 3700U with Radeon Vega Mobile Gfx Memory: 29.3 Gibyte of RAM Graphics Processor: AMD Radeon Vega 10 Graphics Manufacturer: Acer Product Name: Aspire A315-41 System Version: V1.18
