Keyboard shortcuts do not work on a keyboard layout other than English

[Divanovi4]

When switching the layout to Russian, keyboard shortcuts stop working. However, if you switch back, the combinations work

To reproduce. Steps to reproduce the behavior:

1. Server start command:

xpra start :10 --bind-tcp=0.0.0.0:9876 --exit-with-children=yes --start-child="mousepad" --html=off --http-scripts=off \
   --encodings=no-rgb24,no-rgb32 --video=no --min-quality=60 --bell=no --mdns=no --speaker=no \
   --pulseaudio=no --audio=no --speaker=off --notifications=yes --webcam=no --microphone=off --av-sync=no \
   --opengl=no --daemon=no --clipboard=yes --clipboard-direction=both --remote-logging=no \
   --keyboard-backend=ibus --keyboard-layout=ru --keyboard-variant=nodeadkeys

2. Client config file:

	port=9876
	autoconnect=True
	min-quality=1
	host=10.100.0.133
	quality=0
	mode=tcp
	encoding=auto
	speed=0
	min-speed=1
	splash=no
	keyboard-variant=us,ru
	keyboard-backend=ibus

3. Specific action to trigger the bug
   CTRL+C
   CTRL+V
   CTRL+Z
   CTRL+A

--html=off --http-scripts=off

With latest 6.3, try --no-http.

--speaker=no --pulseaudio=no --audio=no --speaker=off --microphone=off --av-sync=no

Same as audio=no

--notifications=yes

Is the default.

--webcam=no --opengl=no

Probably not useful.

--clipboard=yes --clipboard-direction=both

Is already the default.

When switching the layout to Russian

How?

[Divanovi4]

I switch the layout by pressing CTRL + L_SHIFT, or L_ALT + L_SHIFT, or by switching through the WIN 10 tray. The result is the same.

Update: I also found that the combinations do not work when Caps lock is pressed (regardless of which language is enabled)
