Hello,

I have started seeing this crash in the past week I believe.

The crash happens when I randomly minimize/maximize the Emacs frame by clicking on its tab in the OS taskbar. I am using RHEL 6.8.

I have yet to find a good recipe to recreate this programmatically.

xdisp.c:21236: Emacs fatal error: assertion failed: it->glyph_row == NULL || it->glyph_row->used[TEXT_AREA] == 0

Backtrace:
emacs[0x5bd0c2]

...

emacs[0x592ea5]
/lib64/libc.so.6(__libc_start_main+0xfd)[0x32f4c1ed1d]

I'll next attempt to recreate this from gdb.

Here is my Emacs build information.

Emacs version: GNU Emacs 27.0.50 (build 11, x86_64-pc-linux-gnu, GTK+ Version 2.24.23)
