[Bug 58658] New: IK Multimedia Amplitube 5: GUI rendering periodically hangs.
http://bugs.winehq.org/show_bug.cgi?id=58658 Bug ID: 58658 Summary: IK Multimedia Amplitube 5: GUI rendering periodically hangs. Product: Wine Version: 10.14 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: emmetoneill.pdx(a)gmail.com Distribution: --- Created attachment 79236 --> http://bugs.winehq.org/attachment.cgi?id=79236 Diagram showing GUI drawing lag spike behavior in Amplitube 5 Amplitube 5 (a guitar and bass amp/effect sim program) has a problem via WINE where rendering of the GUI periodically hangs. Here are some things that might help: - These lag spikes DON'T occur in the original version on Windows. - These spikes seem to ONLY affect the drawing of the GUI. (Audio processing is unaffected, and mouse clicks are still registered even when the rendering is hitching.) - The lag spikes are extremely predictable (dare I say metronomic). From what I can tell they happen almost once per second, every second. They also seem to last about half a second, every time. (I've attached a silly diagram to show how it feels like the spikes are happening.) - I use this program very regularly, and I have noticed that this bug has been around for a while, across a few versions of WINE. I can't say whether or not it is a regression from older versions of WINE as a lot of things have changed on my system, but I'm sure that it isn't new to 10.14. - This may be an interesting, unrelated coincidence... But the default metronome setting in Amplitube happens to be 120bpm (2hz), and the timing of the GUI lag spikes is so regular and predictable that if you turn the metronome on and hit play, you will find that they line up exactly with the timing of the beats/clicks. (Where you can count 1,2,3,4 and visually see the program's GUI draw, lag, draw, lag...) When I first noticed this I changed the internal bpm setting to a different value, thinking that it might be connected, but that did not seem to change the frequency of the lag spikes (they continued happening at ~1 spike per second). - I have tested this on a standard WINEPREFIX containing only IK Multimedia application installs. But I have also tested this using DXVK library overrides. I know that bug reports here are for vanilla WINE installs only, but I just want to mention that this behavior seems to be consistent whether in both contexts. - I should also mention that I don't see any output in the terminal when these spikes are happening. To the untrained eye, there's nothing that I can see that is hinting at what might be causing the visual hitching. Aside from these annoying GUI drawing hitches, Amplitube 5 works very nicely in WINE, so I'm hoping that we can figure something out. :) If there is anything else I can share with the team to help diagnose and debug this problem I'd be happy to help! -- Do not reply to this email, post in Bugzilla using the above URL to reply.

The application runs pretty poorly in general on this laptop and the hitching seems to be worse, so it's difficult to tell how consistent the hitch timing is. (NOTE: This laptop is also running an older version of WINE, 8.19, and the hitching seems to be similar.) This is my first time trying to seriously debug a WINE issue, so please let me know if there is anything else I should try, other WINEDEBUG settings I should use, etc. :) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58658 --- Comment #2 from Emmet O'Neill <emmetoneill.pdx(a)gmail.com> --- I forgot to mention the context of the "laptop log" attachment. While taking this log, I simply opened Amplitube, turned on the metronome click, and then hit the "play" button to start the playback timer. (This is a decent way to visualize the hitching without too many other things going on, i think.) I let the program run like this for a few seconds before hitting the close button, saying "No" on the save prompt dialog, and ending the process. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
