https://bugs.winehq.org/show_bug.cgi?id=44243 Bug ID: 44243 Summary: Spire and Serum paints very slowly Product: Wine Version: 3.0-rc3 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: bique.alexandre(a)gmail.com Distribution: --- Hi, The following programs take a lot of time to render the UI: https://www.reveal-sound.com/ https://www.xferrecords.com/products/serum A few versions before the UI was just black, and recently it started to paint correctly, so it must be that you have add new painting/rendering api recently. Yet the painting performance is really slow, so it would be great if you guys could have a look and optimize it a bit? Maybe it is an easy thing to do? Many thanks for your work guys! To reproduce it you can install a plugin host like reaper: https://www.reaper.fm/ and then install the vst plugins and try them with reaper.
