Disassembly view not working

I'm trying to use the AppImage1.5.1 version (on the Ubuntu 24.04 release). In order to make it work I had to run it with QT_QPA_PLATFORM=wayland, otherwise it doesn't launch. But when I open it there is no disassembly view and every option related to it is grayed out and not clickable.

Screenshots If applicable, add screenshots to help explain your problem.

Version Info (please complete the following information):

• Linux Kernel version: 6.8.0
• perf version: 6.8.8
• hotspot version (appimage? selfcompiled?): AppImage v1.5.1

The disassembly view is only visible after you use it for the first time. To do so you need to right click a symbol, for example in caller/callee or the flamegraph and use the Disassembly feature there.

Oh, didn't see that. But it seem to only work for the "main" function, and I don't see any percentages attributed to any assembly opcode (the "cycles:P" column is empty) (using perf annotate doe's give some opcodes high percentages, but is less readable than hotspot's output)

Is this a variant of https://github.com/KDAB/hotspot/issues/671 maybe? Otherwise, can you share some code and show us how to reproduce the issue from your last comment?
