--- Comment #21 from Stian Low wineryyyyy@gmail.com --- Created attachment 79153 --> http://bugs.winehq.org/attachment.cgi?id=79153 Screenshot of REAPER with 3 instances of Blamsoft VK-1 Viking VST
Attached is a screenshot of Reaper running against my latest patch against 75b9e1722d1 Release 10.13 commit on Debian 13.
The behavior is practically identical to that of Carla and Bitwig.
A minor bug was found which causes the knobs and hover popup labels to flicker to an offset position and back. This is showcased in the screenshot by the "Osc 2 Frequency: 3.8 semitones" label.
The flickering doesn't start until the mouse has settled motionless for 1 to 2 seconds.
I'm reviewing all merge requests leading to this bug report to stage a solution that may be submitted as a merge request.
The virtual desktop workaround seemed the simplest way to fix if not for the dropdown menus opening inside the virtual desktop window instead of the VST window.
The popup labels for knob controls also appear in the virtual window but don't flicker but instead appear and disappear quickly rather than remaining displayed while hovered.
File explorers for VST save/open buttons are also open in the virtual desktop window.
Therefore it seems for virtual desktop mode the effort should be to make the VST windows all appear within the virtual desktop rather than popups appear outside it and aligned with the improperly displayed VST windows.
Whatever virtual desktop mode fixes to make the knobs and controls work for the independent VST windows is a hint what needs to happen when virtual desktop mode is turned off.
