Resizable window weird behaviour

[unborn scarab]

Has anyone else experienced and issue and know how to solve where you use the resizable window setting in unity and when you drag the corners sometimes it leaves black borders where the rest of the screen should be and they also flicker and are partially see through to the Desktop below? Additionally buttons or sliders click zones are offset I.e you have to click below where the button actually is to use it.

I have tried canvas scaling and using only 16:9 and turning off "other aspects" and also anchoring ui to get the desired effect.

Does nobody know? I thought something like this for sure seems like a bug or a glitch but I am surprised no one else has seen it if that is the case

just a question... does this always happens when you drag or does it happens randomly?

only when I drag it and start to resize yeah, if I change to windowed mode and don't resize the borders don't show up on their own and the button click zones are unaffected

😳 can I see your canvas settings?

Sure thing, and these are my player settings, I also tried setting it to start windowed to see if that made a difference vs changing it via Screen.fullScreenMode but sadly the result is the same when resizing

after much googling this code seems to have somewhat resolved it and given the desired effect with one small bit of weird behaviour still https://github.com/wmjoers/CameraScaler/tree/main

Now when I resize using the corners it works much better however I still have the flicker and button offset...until I drag the window a little then it all updates and works but no idea how to trigger that after a resize rather on dragging the window
