SUMMARY When using the cube desktop effect with a skybox that is larger, activating the effect can take 1 second to multiple seconds with a massive (16k) HDRi. STEPS TO REPRODUCE 1. Obtain an HDRi (I am using https://polyhaven.com/a/dikhololo_night , the 4k and 8k version show this off well, the 1k version is fast enough to not be noticable) and set it to be used by the cube effect 2. Launch cube effect OBSERVED RESULT All graphics freeze while loading the skybox EXPECTED RESULT The desktop should not freeze, even if it takes time for the file to get loaded SOFTWARE/OS VERSIONS Linux/KDE Plasma: Neon (available in About System) KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION The HDRi is on an SSD, with an r5 5900x and rx 6700xt so low hardware specs I don't think are the issue In my opinion, the 8k version of the skybox is the minimum to be good on my 1080p screen
Can reproduce the issue with that skybox image.
