First problem I found:slider texture disappears/misplaces when selected
mentioned in
this thread
repeatable across a variety of mapsets
Second problem (may not be a problem):in borderless mode, when i edit a map and then exit out of it without saving, the entire osu window minimises
third problem (having trouble replicating)When the second problem happens, there is a case where the editor background turns completely black. No matter what button you press (exit, yes, no, cancel) you cannot close the editor/osu and it just minimizes. alt+f4 doesn't work and must close by ending osu.exe process. This would probably affect people who read mods on their map, apply them, and forget to save before closing resulting in a lot of map changes lost.
A replicate method for problem three would be the following:
1. Launch osu! in borderless mode
2. Open editor and open up any map
3. move any element in editor (circle/slider) on the playing field
4. alt-tab to a window which is maximized (eg. maximized google chrome, maximized windows explorer, etc.)
5. alt-tab back to osu!
6. press esc
7. problem appears
I don't know if this method is reliable, but it happens to me when I do it
edit: problem one has been solved in next update but problem two and three still persist (maybe it's just me)
