SUMMARY I can reproduce only if display scaling facor is 1.2, only flatpaks from flathub are affected. Weirdly nightly flatpaks from kdeapps repo are not affected. STEPS TO REPRODUCE 1. set your display scale to 1.2 in system settings > display and monitor > "scale display" button. Restart plasma. 2. open discover, click "settings" in the side bar, click "Flathub" repo to show its packages 3. click some flatpak to open its description, click some screenshot OBSERVED RESULT We can see a spinner while the screenshot is loaded. The spinner position changes as it rotates. Watch the screencast please. EXPECTED RESULT spinner position should not change while it rotates. SOFTWARE VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.14.1 Qt Version: 5.11.2 KDE Frameworks Version: 5.51.0
Created attachment 115685 [details] demonstration
I can confirm that, though the spinner is even more eccentric to me with a scaling of 2. Operating System: Manjaro Linux KDE Plasma Version: 5.16.4 KDE Frameworks Version: 5.62.0 Qt Version: 5.13.0
Seems to be fixed with fractional scale and integer factors now.
