Modifier keys LCTL, LSFT etc. not working under windows remote desktop

[AnaMarkH]

Issue Description

Hi,
in my keymap I use e.g. LCTL(KC_V) and LSFT(KC_MINS) which work fine under Windows.
However, when using Remote Desktop, the modifiers are no longer recognized, i.e. LCTL(KC_V) outputs KC_V only etc.

I assume that Remote Desktop requires some additional delay between pressing LCTL and KC_V.

I tried

void oneshot_mods_changed_user(uint8_t mods) {
	send_keyboard_report();
}

but without success.

Is there any other way?

ArijanJ thank you for the link. However the solutions suggested there make it even worse:

open Remote Desktop Connection, click on "Show Options", open the "Local Resources" tab, and in the keyboard section, change the drop down to "On this Computer".

This disables some key combinations I often use, e.g. Alt+Tab. So I have to jump between mouse and keyboard all the time.

It can also be mitigated by increasing TAP_CODE_DELAY

Indeed when setting TAP_CODE_DELAY to 200ms, the remote computer recognizes most (not all) mod-key-combos. But it interfers with bottom/home row mods. E.g. when using LALT_T(KC_M), it is impossible to enter a double-m or any other character following the m-key, even with moderate typing speed: the second key is always lost.

Meanwhile, my qmk keyboard has found its place in the office, so I don't use it with Windows Remote Desktop any more.
