UI messes up when fullscreen (and window mode after fullscreen)

[0lm]

Describe the bug I encounter this bug for years now and hoped it would be solved with the newer versions, but I think it remained unnoticed. When double clicking video (to make it full screen) the while GUI changes into black, not visible anymore when playing a video. And when going back to window mode afterwards, the colour patterns/style of seekbar and buttons change. This all reverts back when closing smplayer and opening again. But the moment you fullscreen the video, it messes up the styles again. This happens with both multimedia engines. It seems like only "MPC Gui" is affected.

To Reproduce Steps to reproduce the behavior:

1. Set GUI to "MPC Gui", Icon Set to "Default" and Style to "Fusion" (I think the Style doesn't matter actually)
2. Fullscreen Video
3. Make it WIndow again

Expected behavior Keeping its set style

Screenshots
