Plugin UI disappears and crashes reaper on linux
muziker opened this issue · comments
On linux and in reaper, plugins can be run in 3 modes: separate processes, dedicated processes, native only ( without bridging).
In all these modes, the VSTPlugins UI appears, but if the GUI is closed and reopened, only sliders of the UI appear, everything else is blank. Occasionally reaper crashes but usually the audio gets stuck and plays the same buffer all the time.
I've applied the cairocontext patch to vstgui4 but not the fedora patch as indicated in the build instructions.
vstsdk 3.7.3
Thanks for the report.
I'll make a VM to test this issue. Could you provide following information?
- Linux distribution and version
- Reaper version
- VSTGUI version
VSTGUI version is available on vst3sdk/vstgui4/vstgui/lib/vstguibase.h.
ubuntu 20.04 , reaper 6.47, vstgui 4.10.3
It seems like a bug on REAPER, so it's probably better to report on REAPER forum.
I tested with a AGain VST3 on REAPER. AGain VST3 is an example plugin bundled with VST 3 SDK. AGain crashed the same way as my plugins.
Environment
- Fedora 35
- REAPER v6.53/linux-x86_64 rev 3923c1
- VST 3 SDK 3.7.4 (commit d821ee6)
- VSTGUI 4.10.3 (commit 6431f630)
Steps to reproduce
- Open REAPER
- Load an AGain VST3 to mixer.
- Repeat open/close AGain VST3 GUI.

I also tested with sfizz on REAPER, but it didn't crash. sfizz is using their own fork of VSTGUI, so it might be the reason.
This issue has same root cause of issue #16. The crash can be patched for next release of Uhhyou Plugins. See the issue above this comment.
I added ci/linux_patch/x11frame.cpp.diff to patch the bug, and updated build instruction. It's working on Fedora. Please let me know if it works on your environment.
