Bug ID: 56444 Summary: Plogue sforzando GUI is always one animation frame behind Product: Wine Version: 9.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d2d Assignee: wine-bugs@winehq.org Reporter: s_chriscollins@hotmail.com Distribution: ---
Created attachment 76204 --> https://bugs.winehq.org/attachment.cgi?id=76204 video showing the bug
The free VST plugin Plogue sforzando always lags one animation frame behind what it should be. I believe this might only happen with NVIDIA GPUs, as the issue does not occur on my laptop (radeon driver) or in VirtualBox. Please see the attached video for a demonstration of the bug.
STEPS TO REPRODUCE 1. Download and install Plogue sforzando: https://www.plogue.com/downloads.html 2. Launch "sforzando x64" from the application menu. 3. Click on the tabs and keyboard keys.
ACTUAL RESULT The GUI always displays the preceding frame generated by the application, but not the current frame, making things appear laggy/unresponsive, etc.
EXPECTED RESULT The GUI should update as soon as I click on an interactable element.
