User interface is running at low fps, probably <25-30fps

[pushqrdx]

I tried both with and without opengl but for some reason panning is stuttery and overall fps is really low, I also tried with and without x11 compositor running

i can't get LIBGL_SHOW_FPS to actually print fps, and using LIBGL_DEBUG doesn't print anything suspicious but here's what it prints anyways

One thing that comes to mind: if you're building the app from source, note that the default build configuration is Debug, which is quite slow even with OpenGL enabled. If this is the case, you'll want to build it like CONFIG=Release64 make all strip

@peterrudenko i am using the prebuilt packages from the website

I can confirm this on NixOS, opengl renderer is even slower than x11 one.

I saw that JUCE based DAWs (like the Helio and Tracktion Waveform) have very bad performance with OpenGL render in Linux X11 (hadn't test it in Wayland). Moreover it may hang with some old GPU. What is your GPU? On NVIDIA you can toggle FPS display via nvidia-settings. Also check your CPU usage at first with top, i see 100% load with OpenGL render time to times.

@KottV i tried both on intel igpu and an nvidia, Helio is so slow and performance is beyond terrible. on windows it is running perfectly smooth
