Created attachment 146073 [details] The slow loading in action SUMMARY When I super+tab, the thumbnails of different activities often take longer to load than it takes me to switch to another activity. Most likely happens because I'm using very high res wallpapers. All of them are bigger than 5120x2880 and vary in file size from 2.4 MiB to 16.8 MiB. If it is impossible to load the wallpapers quickly enough, there should be a way to cache down-scaled versions of them for such time sensitive uses. STEPS TO REPRODUCE 1. Super + Tab OBSERVED RESULT Grey rectangles that become colored rectangles after a good delay EXPECTED RESULT Colored rectangles SOFTWARE/OS VERSIONS Operating System: Garuda Linux KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.16.3-zen1-1-zen (64-bit) Graphics Platform: X11 Processors: 8 × AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx Memory: 5.7 GiB of RAM Graphics Processor: AMD Radeon Vega 8 Graphics
