Intellisense stops working every second character

[artembon (baj)]

Intellisense just dips out every second character typed. The issue appears seemingly randomly.
See the gif attached:

Specs:
CPU - AMD Ryzen 7 5700X 8-Core Processor
GPU - NVIDIA GeForce RTX 3060 Ti 8 GB
Memory - 32GB 3200MHz

Expected behavior

Intellisense is visible the entire time while typing the property

Hi @artembon Would you check what beta feature you are enabling? Especially for the “Incremental typechecking”

Thank you!

I’m seeing this bug with the beta enabled.

Thanks for pointing me in the right direction! I’ve played around with the beta features a bit, and found out that this problem is actually a mix 2 problems! As you noted, Incremental typechecking beta feature was in fact on. I disabled it, and intellisense stopped displaying completely in that place in code. After some testing, I figured out that the “New Luau type solver” beta feature completely breaks intellisense, but “Incremental typechecking and autocorrection” fixes it; you mix the two, and get the strange result that is this post. So, the “New luau type solver” beta feature is actually the one at fault.
I’ll try to add a code snippet where this happens when I’m home.

@yohooyohoo
While I was copying the code I figured out the exact place where it was happening. Here’s what I found:

local function foo(): any
-- function that has return type of anything other than Instance or PVInstance
end
local variable: PVInstance
variable = foo()
-- bug starts appearing after variable is assigned to foo()

Still an issue:

Hi @artembon, thanks for reporting this! We just released a fix to mitigate the issue—suggestions should no longer disappear after typing the second character. The root cause was a difference in autocomplete behavior introduced by the new type solver, which we’re still actively working on.

Please let us know if you continue to experience the “IntelliSense disappears every second character” issue.

Thank you!

@Withoutruless This should now be fixed. Suggestions should remain consistent while you’re typing. Thank you!
