OS/2 video perfoemance is notably degraded after linux upgrade

Description (last modified by aeichner) (diff)

openSuse v11.3
linux 2.6.34-12-desktop x86_64
amd athlon x4 (630)
ati radeon hd3200 (built-in)

After upgrading the OS to openSuse v11.3 from 11.2 the graphics performance for an os/2 VM is noticeably degraded. There seem to be unwarranted delays in updating the screen that make the appearance quite jerky whereas before it was fairly smooth.

VBox 3.2.6 was running before and after the upgrade.

One of the major changes in the new OS release is the open source Radeon video driver. I assume there is a connection between the two.

This also affects the mouse pointer. The host's mouse icon is no longer suppressed when mouse integration is enabled. So I have two pointers whenever the os/2 VM has the focus: the host's default pointer, and whatever is appropriate in the VM.

Well, all points to the updated display drivers. Not sure why you're opening a bug for VirtualBox in that case.

AFAICT only VBox is affected by the updated driver.

I have noticed a similar effect in a windows VM but it is not as objectionable.

As a workaround I have changed video drivers. I installed the ATI proprietary fglrx driver and the video performance has returned to acceptable level.
