BasicLimiter 1.5 quirks on Carla 2.4.3
windowsrefund opened this issue · comments
Hello,
OS: Ubuntu 21.10
Window Manager: i3
Carla: 2.4.3
BasicLimiter: 1.5
The GUI is showing some quirky behavior. First, it always loads in a "cut off" fashion on the extreme left side of my monitor. I'll attach a screenshot showing what I see.
I can grab the GUI with ALT+mouse in order to drag it into the middle of my screen. From there, no presets seem to be available despite the fact I've placed them in the correct location.
➜ ~ find .vst3/presets/BasicLimiter
.vst3/presets/BasicLimiter
.vst3/presets/BasicLimiter/Default.vstpreset
.vst3/presets/BasicLimiter/Truepeak.vstpreset
.vst3/presets/BasicLimiter/HalfTheTheory.vstpreset
After closing the GUI, any attempt to open it again now renders the same problematic GUI (left-middle, cut off) but this time with no text. In order to fully see the content of the GUI, I'd have to reload the actual plugin from within Carla. Actually, I did this and Carla crashed.
Honestly, I do tend to think this is more of a Carla problem but the issue I filed is getting no attention. I just figured I'd check in on this side.
Thanks in advance.
Hi.
The behavior of "once closing and opening again crashes the host" sounds similar to the issue #14 (REAPER on Linux). Could you get a stacktrace from core dump? Following command might be used.
coredumpctl list # Check the PID of target core dump.
coredumpctl debug $PID # Replace $PID to the one obtained from above.If the problem is the same with #14, then _get_screen_index will appear on stacktrace.
I'd also like to know where did you get the plugin binary: did you build it locally, or downloaded from manual page?
Edited to fix the command.
I'll check the preset behavior later.
I confirmed same issue on Carla 2.4.3 on Fedora 36.
The cut off to extreme left side is a issue specific on Carla. I also tested with sfizz, and sifzz also shows up on extreme left like your screenshot. REAPER doesn't show this behavior.
It seems like both Carla and REAPER don't support VST 3 preset path on Linux. However, REAPER can load the *.vstpreset files. I couldn't find a way to load presets on Carla. I made my presets on VST3PluginTestHost provided by Steinberg. The preset path is defined in the VST 3 spec below.
Off topic but even Ableton Live 10 wasn't able to load VST 3 presets created on VST3PluginTestHost. I guess this is one of the problematic part of VST 3. That fancy ascii art in preset format documentation was not entirely accurate last time I checked. Probably outdated. For reference, I wrote a vstpreset to JSON conversion script for LV2 repo.
On the crash at re-opening plugin window, I got a stacktrace which contains _get_screen_index. The stacktrace is on the bottom of this post. This issue wasn't present on VSTGUI 4.9, so I guess VSTGUI 4.10 or later introduced some change. Also as same as REAPER, Carla crashed with AGain VST3 which is a example plugin of VST 3 SDK.
I strongly recommend not to load my plugins, and any plugins using VSTGUI 4.10 or later until this issue is resolved by plugin hosts or VSTGUI. The crash can severely break the window manager like following (I'm on Openbox). Those Unnamed Windows are created by opening AGain VST3 GUI, and can't be closed by clicking "x" button on top right.
Environment
- Fedora 36
- Carla 2.4.3
- VSTGUI 4.11
Steps to reproduce
- Open Carla.
- Load an AGain VST3.
- Repeat opening and closing AGain VST3 GUI.
Stacktrace
Following stacktrace is obtained from AGain VST3.

Extremely informative. Thank you very much for the information.
Some update on this issue.
The crash can be patched for next release of Uhhyou Plugins. See the linked issue above this comment.
Unnamed Window issue seems like Carla specific. It might also be specific on Openbox, but not confirmed.
The re-opening crash is patched now. You can download binary from latest release, or build from source code (build instruction). Please let me know if it at least doesn't crash on your environment.
I see the following quirks with 1.9:
- Still opens in the same undesirable location (cut-off, middle-left side)
- While it does seem a bit more reliable in terms of being able to open and close, it is slow as mud to render.
- From what I'm reading above, presets won't work?
Given the above, I just don't understand why you're wasting your time with VST3. I mean, I guess you want to cater to the windoze/mac crowd?
Thanks for testing. The rest of issues are on the plugin hosts.
I close this issue since the patch for the crash was merged to VSTGUI.
I probably stop using VST 3 SDK directly when JUCE or other framework starts supporting fractional pitch, note expression, and host context menu. Also GUI issue can occur regardless of plugin format.
