[app_server] crash in HWInterface::_CopyToFront

[diver]

When using VESA mode I tried to change resolution app_server crashed in HWInterface::_CopyToFront.

Segment violation
Switching to team /boot/beos/system.servers/app_server
HWInterface::_CopyToFront
HWInterface::CopyBackToFront
AccelerantHWInterface::CopyBackToFront
HWInterface::Invalidate
HWInterface::MoveCursorTo

I've seen this too once. Thanks for reporting.

Hi,

I have the same (or I think it's the same) error here on hrev30464.

Can confirm having had something similar yesterday (something before hrev30464). Not in HWInterface. Never seen this before. Log got lost unfortunately.

Never saw it again, but I don't change resolution as it always correct.

In the last few days I have run into a similar crash on boot (with qemu, 2 CPUs) a few times:

The latest version tested with was a PM Haiku equivalent to master hrev46085.

(In #12323) Most likely a duplicate of #2539.

(In #12749) Thanks, closing as duplicate of the 2 others then.
