Should this code really have a > lock at all? There are two different kinds of "locking" going on here. There's GdipLockBitmapBits, which isn't a locking mechanism at all but a way of accessing bitmap data, and the mutex we have protecting Bitmap objects. Also, error 7 is a gdiplus Status enum value named Win32Error, not a win32 error code, so this isn't ERROR_ARENA_TRASHED. This test case is entirely single-threaded, so it's not a race condition. The mutex-lock isn't really involved. It seems like gdiplus does not account for GdipImageRotateFlip being called while a bitmap is bits-locked. I would guess that RotateFlip changes the location of the image data, invalidating the state that UnlockBits needs to function correctly. What "should" happen in this situation is probably that GdipImageRotateFlip fails with WrongState, but it seems Windows doesn't do that. The patches here bring us closer to the (broken) Windows behavior, although I'm really not sure how Wine will end up handling this situation in practice. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1003#note_12125

Thank you for checking. That behaviour sounds an awful lot like gdiplus isn't thread-safe after all. E.g. error 7 is ERROR_ARENA_TRASHED. Should this code really have a lock at all? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1003#note_12119

[PATCH v2 0/1] MR1153: winex11.drv: Correctly handle clipping for fullscreen windows.
by Gabriel Ivăncescu Oct. 25, 2022

Oct. 25, 2022

When we are clipping (due to fullscreen), certain operations are bugged (such as creating another window on top, grabbing the window during a size-move operation, changing mouse capture, etc) so we must temporarily unclip first. Seems unclipping it temporarily during such operation is enough to fix this. This probably wasn't very obvious in practice because most times "fullscreen" means a single non-resizeable window with no menus and so on (e.g. fullscreen games), but that's not always the case. -- v2: winex11.drv: Correctly handle clipping for fullscreen windows. https://gitlab.winehq.org/wine/wine/-/merge_requests/1153
