Summary0008459: Ardour crashing with message GUI POOL OUT OF MEMORY
DescriptionI recently downloaded the new version (1 month ago) and I'm getting repeated crashes where I'm shown the message below in an alert box:

"CRITICAL: GUI POOL OUT OF MEMORY - RECOMPILE WITH LARGER SIZE"

Trying to reproduce the bug I notice it happens when I start to edit a MIDI track. More specifically, when I try to edit velocity in MIDI notes. If I work on audio tracks, nothing happens.

I begun a project recently and worked entire days without crashes. Went for edit some MIDI notes and the crashes started again.


Steps To ReproduceCreate MIDI track, add notes and change velocities. Not sure yet this is the main cause, but right now it is to me.
TagsNo tags attached.

Is it possible to edit the issue?

I forgot to inform my OS version, which is 20.04.

I did a few tests and noticed the bug happens when you try to change the velocity of a MIDI note through the mouse (clicking the note and scrolling with the mouse tracker) .

If you edit the velocity in the "Edit" window, right-clicking the MIDI note, nothing happens.

Since I did this in Ardour 5 without any problems I guess the bug is related to the new features added in 6.3, regarding MIDI notes. For example, in the new version the velocity of a note is shown as a little bar inside the note and changes width dinamically, as we roll with the mouse.

The underlying issue is that the GUI queues up events for others to process. But you produce events faster than others (backend, ctrl surfaces etc) can process them.

Do you perhaps have any Ctrl surfaces enabled (Preferences > Control Surfaces > ...)

Then again repeat MIDI edits might also be able to trigger this, if re-reading the MIDI files takes too long.

Hi, thanks for answering.

"Do you perhaps have any Ctrl surfaces enabled (Preferences > Control Surfaces > ...)"

No, i wasn't even aware of that option.
