Chinese input in edit and memo in Linux is incorrect

(1/1)

myisjwj:
There is no problem in entering English, but errors will be reported when entering Chinese.

Pango:ERROR:.. /pango/pango-layout.c:4606:get_items_log_attrs: assertion failed: (item->length <= (start + length) - item->offset)
Bail out!  Pango:ERROR:.. /pango/pango-layout.c:4606:get_items_log_attrs: assertion failed: (item->length <= (start + length) - item->offset)
Aborted (core dumped)

Another problem is that it works when you use Memo in the main window. If there is a memo control in the new form, it will randomly error and automatically exit the application.

The input method is fcitx.

myisjwj:
The problem is found. If the form contains a Tmemo control, use Form1.Show. Or if the panel contains Tmemo, use Panel1.Visible:=True; There will be problems. Use panel 1.bringtofront; There won't be a problem. The reason is not known.

myisjwj:
All the reasons found. Under Linux can not operate in the event the main thread of the UI, can only use the Application. The QueueAsyncCall to operate.

AlexTP:
- What widgetset, gtk2 or qt5 or qt6?
- Wayland or X ?
- What OS distro and version?

myisjwj:
gtk2
system arm64:ubuntu18,UOS,Armbian 23
system x86:centos7
CPU:x86_64,arm(armhf)
The above systems and cpus have been tested. X86 has fewer problems.
