Description Toadfield 2021-06-06 20:50:59 UTC

When I enable the fullscreen effect,then when I make a window in fullscreen,then one of those things happen:
1.The title bar gets transparent shortly.
2.The whole window gets transparently and I can see my desktop shortly.

I can't reproduce this issue with the Breeze theme. Are you using any non-default themes? Can you attach a screenshot that shows the problem?

Also, what version of Plasma are you using? It would be helpful if you filled in that information when you file bug reports.

This issue only happens on firefox,so it is probably firefox specific,I will report a bug over there,so you can close this issue here (or can the op's themself close issues?)

Don't close it,it is not a firefox issue,it also happens on other programs.
It looks like this when a program uses qt borders https://i.nuuls.com/qUJDX.png or this when it uses gtk borders https://i.nuuls.com/YQIoN.png when I maximize a program for a short time.

Are you using any non-default themes? If so, does it happen with Breeze?

Comment 5 Toadfield 2021-06-11 18:29:21 UTC

It also happens with Breeze.

Comment 6 Nate Graham 2021-06-14 18:41:28 UTC

Can you please attach a screen recording that shows the problem?

Comment 7 Nate Graham 2021-06-14 20:02:01 UTC

Actually I can reproduce with all apps that have a Full screen mode.

Cross-fade animation is implemented as a hack at the moment. We plan to fix it in 5.23.
