Created attachment 183089 [details] A Screencast Which Demonstrates The Difference Between Full-Screen And Window-Specific Screencasts, And Confirms The Greenness I've attached a screencast that demonstrates that it's green, in case you somehow don't see it on your end (like if it's a decoder fault).
Created attachment 183090 [details] A Screenshot Of Dolphin Not Reproducing This In Its Player This doesn't affect Dolphin (when playing; not merely the thumbnailer) and Gwenview. I presume that this should be closed, and refiled at https://code.videolan.org/videolan/vlc/-/issues/new? Apologies for being a little quick, but this is probably best, since I can't myself ascertain whether Spectacle is doing something strange, or VLC is deficient.

I have seen a weird green coloring issue before in Spectacle's own video player, but it eventually went away. In my case, they were green bands rather than the whole image being green. It's probably a decoder issue as you said or driver related issue since there is usually some degree of accelerated decoding for the video formats supported by Spectacle.
(In reply to Noah Davis from comment #5) Thanks. Considering that VLC utilises custom decoders that it includes via a library marked as a mandatory dependency of the package, I've filed https://code.videolan.org/videolan/vlc/-/issues/29210.

(In reply to Roke Julian Lockhart Beedell from comment #6) Setting as RESOLVED MOVED, since solely VLC struggles with this.
Created attachment 184494 [details] A Screenshot Of `spectacle-6.4.4-1`'s Thumbnailer Rendering Mostly Green Lines On Greyscale (In reply to Roke Julian Lockhart Beedell from comment #6) I think VLC might merely have been a symptom. I'll tentatively reopen, for the attached screenshot of `spectacle-6.4.4-1` appears to demonstrate that its previewer is affected, too.
This is a Qt bug: https://bugreports.qt.io/browse/QTBUG-138679
(In reply to Nate Graham from comment #10) Thank you! Do you reckon that both behaviours โ the full-screen green overlay (especially in VLC), and the newfound artefacting in Spectacle โ are the same? I hoped I hadn't conflated them, but I'd like to confirm. If they're both caused by that issue, I'll close the VLC report, too.
Yeah, they're the same.
