SUMMARY When playing a video, for example with mpv, when I go full-screen, it is instant without a smooth transition/animation. Leaving full-screen shows a smooth transition and from this point on, going full-screen and back is always a smooth animation. STEPS TO REPRODUCE 1. Play a video with MPV. 2. Go full-screen (f). OBSERVED RESULT First time going full-screen is without transition/animation. EXPECTED RESULT I expected a smooth animated transition when going full-screen. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.21.2 KDE Frameworks Version: 5.79 Qt Version: 5.15.2 ADDITIONAL INFORMATION I noticed this behavior on Firefox as well and video's on the web. IMPORTANT TO NOTE: I also discovered this bug only happens on initial window creation. If I move the window around first and then go full-screen, the smooth transition does happen. But if I don't move the window, the first time going full-screen is always instant and without animation.
Apology if something is wrong here. I am new to KDE and even newer to bug reporting. Feedback if I did something wrong is much appreciated.
I can reproduce the issue, but it appears to be MPV's fault for overriding the defaults. Please report this to the MPV developers. Thanks!

Just checked with SMPlayer and MPlayer and they do indeed show the animation. Then I guess with Firefox it is the same then? Since there it also does not happen initially.
To clarify, in Firefox I mean using the full-screen button on video's like on YouTube for example. Pressing F11 works with the animation, but using the full-screen button on a video does not show it the very first time.
Yep.

I made a report on mpv (https://github.com/mpv-player/mpv/issues/8652#issuecomment-799589058) and they are asking what default is being overridden. Are you able to specify that? Then I can inform them. :)
