All docked components in the UI disappear

[leandrosansilva]

Describe the bug
All the visual components disappear after I tried to drag the window and there is no way to restore them.

To Reproduce
Open hotspot.

drag the docking components around. Make mistakes and they disappear.

After a few attempts, they all disappear.

When I click on "window -> top down", the top down dock appears in a different window:

But there is no option to show the other docked components, such as the flamegraph, etc.

Expected behavior
I would expect the docked components not to disappear.

If forbidding them of disappearing is too difficult, I think that some way to "restore default layout" would be enough, as I could always to back to the original state of the UI in case of mistakes.

Unfortunately I am profiling some large perf.data (multi gigabyte) that take hotspot several minutes to open

Screenshots
Posted above.

Version Info (please complete the following information):

• Linux Kernel version: 6.4.6
• perf version: 6.3
• hotspot version (appimage? selfcompiled?): 1.4.1 from Manjaro/AUR
• if self-compiled hotspot, what version of elfutils: 0.189

Additional context
I am opening a perf.data that has been recorded on a different host, so I do not have access to all the debug symbols.

Apparently there is a way to restore the layout as described on #473, but it seems the changes have not yet been released. I'll try to build hotspot from master and try it again.

Closing as when building Hotspot from master the Restore Default Layout menu option works for me when I mess up with the layout :-)
