+++ This bug was initially created as a clone of Bug #466683 +++ Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.14-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-7820HQ CPU @ 2.90GHz Memory: 31,1 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 630 Setup: Laptop with 2K Laptop screen and a fullhd screen (1920x1080) connected by displayPort Use fullHD monitor as 'primary' and perform all tests on the fullHD monitor (ignore laptop screen) Go to systemsettings > display config and set 175% scale for 2K laptop screen, 100% for fullhd screen. This makes apps/windows on both monitors the same visual size. Problem: - in dolphin, open the /usr/share/wallpapers/Next/contents/images/ dir and press F11 to show the (initially hidden) image preview. This destroys the whole dolphin window contents (making it unusable because of missing buttons/list-panels or symbols) until you close/reopen dolphin. Then it works ok.
Cannot reproduce with an identical setup (excepting the small differences that my external screen is HDMI not DP, my Intel iGPU is a 620, and my CPU is a i7-10510U).
i must admit that i cannot reproduce this either (i already updated in the meantime, maybe the kf5 22.12.3 update had an impact?) I'd say... let's close this issue for now
