LS 3.1.0.0 doesn't function at "Scale" pressed, crashes at "Unscale"

[hard pivot]

When "Scale"/hot key pressed, application will stay same as it's size / frame, leaving a space of taskbar.
When "Unscale", mouse cursor limited to the application size. Alt-Tab can release the cursor, and LS will exit(crash). There will be some LS icon left at minimized tray, and will gone as soon as I checked there.

environment:
Win 10 X64 22H2
Nvidia GeForce GTX 1050 Ti

setting tested:
default
Capture API > DXGI / WGC
Scaling > LS1 / FSR
Frame Generation > Off / LSFG 3.0 / 2.3

basically neither scale or FG works on LS 3.1.0.0
also tried reboot, update GPU driver
please tell me if there's more detail needed

are you running the game full screen by any chance

[hard pivot]

no, runs in windowed mode

[meager bridge]

can u record this so we can see whats happening?

[hard pivot]

I decided to go genius because I remember screen capture interfers LS, and there's 100 MB limit so the record's in a hurry, sorry

I rolled back to LS 2.12, it worked for me

for me, i never use Scaling and i use dxgi X(

[hard pivot]

DXGI worked for me, until a certain windows update (about the time announcements mentioned MS changed something w/ DXGI) now only WGC works (3.~ before 3.1.0.0)
None of them, with/without scaling work now 😦

Well that's weird

WGC no longer supported before Windows 11 24H2 and fallbacks to DXGI.
What is the game name you testing on?

[hard pivot]

it's called "Enjoy the Diner,＂ a relatively niche game. I've tested on Resident Evil 2, too. And I often use LS on YouTube PiP to scale/double frame.

scale youtube - not affect, crash when unscale
scale RE2 - no scale, black baackground, crash when unscale
LS in tray stays until checked, they stacks
keyboard sound marks the time I scale/unscale

Hi, I'm using Win 10 22H2, and only WGC works back them(previous version, LS 3.0.~?)
maybe it has something to do with MPO support?
None of them work on current version. I've recorded some more with DXGI.
Can we have LS 3.0.~ in legacy channel at the meantime, too?
