Cursor misplaced when typing mid-blink

[galefino]

Bug Description:

While typing into Theia, and waiting for the cursor to almost reappear post-blink, the cursor will be placed in the wrong position, to the left of the recently typed character.

Steps to Reproduce:

1. Open a file in Theia.
2. Start typing.
3. Wait for the cursor's blink - It seems to have to be precisely near the end of it
4. Pay attention to the cursor's position.

Attaching a video - Sorry in advance for the quality and blur:

Additional Information

• Operating System: Linux
• Theia Version: 1.30
• Browser: Firefox v102.5.0esr, Chrome v108.0.5359.125

Hey @galefino,

can you check whether this issue still appears when using the latest master? We updated the monaco integration in 1.32.0 (see #11787). It might be that it's an upstream monaco issue and in this case it could that the update already fixed this.

Will do! I'll update later today. Thank you for the quick response!

Hi @msujew!
I'm now using 1.33.0 from master, and the issue persists.
Thanks in advance!

I am having trouble reproducing this error in the latest master. Does it still persist?
Windows Version: 10.0.19045 Build 19045
Theia version: 1.35.0
Default VS Code API: 1.70.2
Firefox: 102.9.0esr (64-bit)

I've been unable to reproduce it and we've had several updates to our monaco package since then. I assume this has been fixed in the meantime. If that's not the case, please comment here.
