Bug ID: 50733 Summary: MUSICUS!: ending videos play are extremely choppy Product: Wine Version: 6.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winegstreamer Assignee: wine-bugs@winehq.org Reporter: pernegger@gmail.com Distribution: ---
When testing if 6.3 fixed #50686 I noticed another performance issue / regression: MUSICUS!'s MPEG1 ending videos are extremely choppy in 6.3. They're not very dynamic in the first place, so it's hard to tell what's wrong, but the audio (ending song) is fine, and the video (lyrics) are more or less in sync, so I'd say lots of frames are getting dropped, but I couldn't swear the whole thing isn't running a tad slow, too.
6.0 is *much* better. If I open the video in VLC directly, it is a bit smoother still, but without a direct comparison I wouldn't have noticed. This is on a Ryzen 7 3900X [Ubuntu 18.04.5].
(Then I remembered that I had this issue on my "laptop", too. That's a Surface Go 2 [Ubuntu 20.04], currently. Only it was *much* worse, totally unwatchable, we're talking a new frame every other second, maybe. I chalked it up to the machine being too slow, but maybe not. It's not just MUSICUS!, either, I retrospect one or two other (older) visual novels showed similar symptoms -- I just assumed the videos were crap at the time. Note that this bug is strictly about MUSICUS!, when that test case is fixed, I'll happily go back and test the other stuff, the tangent is just meant to illustrate that hardware performance may play a role in how noticeable it is.)
[#50239 has slightly different symptoms, and most importantly, I'm using MUSICUS!'s 64-bit exe.]
The regular terminal output has nothing, please advise on how to get suitable debug logs.
