Is your distro (?) GUI X11 or wayland based?

Distro is Manjaro I3 edition, which is X11 based.
I will test 4.x RT-kernel tomorrow. Am i only one suffering from this?

Interesting,
Can you describe your system's spécifications, which soundcard do you use and which sample rate?
32 buffer is very, very low. IMO, not necessary.
Anyway, I will test on my system.

Sample rate = 48kHz
Soundcard = Focusrite Scarlett Solo

I have low-latency fetish

Tests:

JACK buffer Size 32:
1. GUI visible - Xrun on every keypress
2. GUI not visible - no Xruns

JACK buffer Size 64:
1. GUI visible - occasional Xruns
2. GUI not visible - no Xruns

System Information:
Linux Kernel 5.2.10 RT
Pianoteq v6.5.4
CPU governor performance

My whole system runs trough JACK e.g. i can watch movies without any XRuns. Thus i think it is fair to call this behavior a bug.
