Mozilla/5.0 (X11; Linux x86_64; rv:104.0) Gecko/20100101 Firefox/104.0 ID:20220712215641
Ubuntu 22.04, Wayland session & xwayland Firefox nightly

In a google doc document, what is displayed on screen is not synced with what I type on the keyboard.

STR:

1. Create a google doc
2. type something
3. press Enter key

ER:
What I type is what I see

AR:
There is a one letter delay between what I type and what I see on screen, for example the last letter of a word is actually displayed with a blank space, the letter will be displayed only after I type another letter

This is a regression by bug 1777426

Setting gfx.canvas.accelerated.async-present to false 'fixes' the bug.

Appears to be Wayland/XWayland specific. I could reproduce with Wayland, but not X11.

[Andrew Osmond [:aosmond] (he/him)]

We aren't shipping accelerated canvas in 104, so I think should be marked as disabled (for beta/release)?

Comment 4

[Pascal Chevrel:pascalc]

We are still in nightly, we will mark it as disabled when 104 is in beta.

Hello,
I couldn't reproduce this issue on neither wayland/xwayland sessions on Ubuntu 22.04 on Nightly 104.0a1(build ID: 20220712215641).
Would you be so kind as to verify if this bug still reproduces on Firefox RC 104.0?
Thank you.
