Revision 9586fefe


Added by aliguori almost 12 years ago

Fix display breakage when resizing the screen (v2) (Avi Kivity)

When the vga resolution changes, a new display surface is not allocated
immediately; instead that is deferred until the next update. However,
if we're running without a display client attached, that won't happen
and the next bitblt is likely to cause a segfault by overflowing the
display surface.

Fix by reallocating the display immediately when the resolution changes.

Tested with (Windows|Linux) x (cirrus|std) x (curses|sdl).

Changes from v1:
- fix segfault when switching virtual consoles with curses
