Subject: [PATCH 1/1] Fix crash on resolution change -> screen dump -> vga redraw (Avi Kivity)
|
|
|
910c5e3 |
|
|
|
3dcd9a4 |
The vga screen dump function updates last_width and last_height,
|
|
|
3dcd9a4 |
but does not change the DisplaySurface that these variables describe.
|
|
|
3dcd9a4 |
A consequent vga_draw_graphic() will therefore fail to resize the
|
|
|
3dcd9a4 |
surface and crash.
|
|
|
910c5e3 |
|
|
|
3dcd9a4 |
Fix by invalidating the display state after a screen dump, forcing
|
|
|
3dcd9a4 |
vga_draw_graphic() to reallocate the DisplaySurface.
