This has happened to me quite a few times:



It happens sometimes when I alt+tab away from osu and then come back to it. I haven't found a reliable way to reproduce it, it seems pretty random, but it always happens that way and is fixed by just moving the mouse.

I play 1920x1080 fullscreen

While ALT+TAB'd out of osu screen for about 20-30 secs and returning i found that the Backgrounds of songs are out of there Proportions (X and Y axis)
Like so http://imgur.com/a/mTEai

it's fixes itself after sometime

Important Stuff
On Osu!Beta
Full screen Letter boxed
Horizontal and Vertical Positions are both 0%
Win 10 64Bit
AMD APU with updated Drivers

Steps to Reproduce

Note: the Reproduction rate is Random;Trosk- tried to do it but couldn't replicate it ! Hasn't been tried on CE. not sure if Letter boxed it Required or its linked to the X-Y positions update.

1. While Full screen Letter boxed and in song selection ALT+Tab out
2. After a brief period of time ALT+TAB back in
3. BackGround Proportions might go YOLO

EDIT: This just happened https://osu.ppy.sh/ss/3536915 it was fixed as soon as i moved my mouse ._.
EDIT 2: its posted in the CE sub forum ._. p/4410737

Regarding Background and other elements can get out of proportion/position after alt+tab'ing out and back in posted here aswell as here.

After having a chat with BeatBreakerS it seems that there's a few requirements to replicate this:
-Raw Input has to be enabled.
-Parallax has to be enabled.
-osu! has to be running in dedicated fullscreen, even in the main menu.
-You must use a device with absolute positioning (such as a tablet).

Once those requirements are met you can replicate it by doing the following:
-Move your cursor around on the main menu with your tablet.
-ALT+TAB out of osu! and do whatever, just move the cursor around a bit.
-ALT+TAB back in.

I guess that this is caused by osu! being unable to apply the parallax transformations while its minimized due to running in dedicated fullscreen, upon maximizing it again you get this messed up transformation.

(Huge thanks to BeatBreakerS!)
