I have a 
Using Linux Mint mate (Linux Mint 19.1 Tessa) 
Linux 4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:39 UTC 2020 x86_64 
x86_64 x86_64 GNU/Linux

We are in Belgium (and ibus-deamon configured for FR-BE keyboard) where we use 
lot of é, è, à and sometime other likes û.
As I'm typing quite quickly and make typing faults, I also use a lot the 
backspace and ctrl+backspace.
As I'm also using the terminals, Shift+Ctrl+v and Shift+Ctrl+v are used a lots 
(sometime by mistake in regular editor like xed). Note that <Control><Shift>e 
is configured for emoticones in the ibus-deamon.

When taping text in xed (2.0.2)... and usually with xed, the ibus-deamon became 
crazy and heating CPU. It is not difficult to me identify it, computer quicly 
raise from 55°C to 80°C (in ~30 seconds).
This happens almost each time with xed, sometine in a minute, sometime after a 
That's completely boring... after several weeks I did need to stop using xed !

As I'm a coder, I also use AtomIDE and I did NEVER have the issue under
AtomIDE... but XED + iBus-deamon are still firing my CPU.

Kind regards,
