The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents [... after about 1 minute, while scrolling down in `vim`] Thread 1 "konsole" received signal SIGSEGV, Segmentation fault. 0x00007ffff7cff3fc in std::__fill_a1<QTypedArrayData<Konsole::Character>::iterator, Konsole::Character> (__first=..., __last=..., __value=...) at /usr/include/c++/11.1.0/bits/stl_algobase.h:912 912 *__first = __value; (gdb) bt full #0 0x00007ffff7cff3fc in std::__fill_a1<QTypedArrayData<Konsole::Character>::iterator, Konsole::Character> (__first=..., __last=..., __value=...) at /usr/include/c++/11.1.0/bits/stl_algobase.h:912 No locals. #1 0x00007ffff7cfd5b3 in std::__fill_a<QTypedArrayData<Konsole::Character>::iterator, Konsole::Character> (__first=..., __last=..., __value=...) at /usr/include/c++/11.1.0/bits/stl_algobase.h:969 No locals. #2 0x00007ffff7cfa65c in std::fill<QTypedArrayData<Konsole::Character>::iterator, Konsole::Character> (__first=..., __last=..., __value=...) at /usr/include/c++/11.1.0/bits/stl_algobase.h:999 No locals. #3 0x00007ffff7cf500c in Konsole::Screen::clearImage (this=0x555555896c30, loca=4302, loce=4319, c=32 ' ', resetLineRendition=false) at /home/hematite/Documents/Build/konsole/src/Screen.cpp:1132 endCol = 89 startCol = 72 line = @0x55555592a048: {d = 0x555555d88340} y = 47 scr_TL = 0 topLine = 47 bottomLine = 47 clearCh = {character = 32, rendition = 0, foregroundColor = { _colorSpace = 1 '\001', _u = 0 '\000', _v = 0 '\000', _w = 0 '\000'}, backgroundColor = {_colorSpace = 1 '\001', _u = 1 '\001', _v = 0 '\000', _w = 0 '\000'}, isRealCharacter = false} isDefaultCh = true #4 0x00007ffff7cf5781 in Konsole::Screen::clearToEndOfLine (this=0x555555896c30) at /home/hematite/Documents/Build/konsole/src/Screen.cpp:1248 No locals. #5 0x00007ffff7d1d08a in Konsole::Vt102Emulation::processToken (this=0x55555594f6d0, token=19205, p=0, q=0) at /home/hematite/Documents/Build/konsole/src/Vt102Emulation.cpp:692 No locals. #6 0x00007ffff7d1a80f in Konsole::Vt102Emulation::receiveChar (this=0x55555594f6d0, cc=75) at /home/hematite/Documents/Build/konsole/src/Vt102Emulation.cpp:474 i = 0 s = 0x55555594f768 p = 3 #7 0x00007ffff7cd8f04 in Konsole::Emulation::receiveData (this=0x55555594f6d0, text=0x55555609f688 " ", length=332) at /home/hematite/Documents/Build/konsole/src/Emulation.cpp:238 i = 75 __for_range = @0x7fffffffd520: {d = 0x555556022050} __for_begin = {i = 0x55555602250c} ``` STEPS TO REPRODUCE 1. Open `vim` 2. Run `:help` 3. Scroll up and down 4. Open and close the `settings` menu 5. Scroll up and down in `:help` 6. Quit `vim` and open the right-click menu 7. Continue to use `vim`/`konsole` for several minutes OBSERVED RESULT Konsole crashes EXPECTED RESULT Konsole should not crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro/Plasma (Wayland) KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.87.0 (Konsole built from source) Qt Version: 5.15.2 ADDITIONAL INFORMATION The crashing seems random, but I'm getting the same backtrace each time.
I can reproduce this after building on master (without rebasing). The issue seems to have appeared in the last day or two.
See https://invent.kde.org/utilities/konsole/-/commit/304305f7529b65d1534b4ee3969fd8fdee26b739#aa0bb420527a32285843c9efd4dd42ab42746bcc_1133_1132
Here's an easier way to reproduce the bug: • Open vim • Press `a` • Hold down `Enter` You can find my .vimrc here: https://github.com/personalizedrefrigerator/dotfiles/blob/main/.vimrc

It looks like https://invent.kde.org/utilities/konsole/-/commit/7bb6e94725c2d5c74fd464a2c120be2a5eb81e15 has fixed thiss!
