*** Bug 738416 has been marked as a duplicate of this bug. *** Another consideration: there was a patch to upstream QXL recently that enables image caching by default, making Spice performance way better with Linux guest. That patch should be included in the update as well. <kem> ok, PM said to go ahead with that plan -- add a comment to 710385 that this is fixed by adding the option to turn off surfaces, which was included in 799524, and then close 710385 as a dup of 799524 *** This bug has been marked as a duplicate of bug 799524 *** One would expects that the right way is to fix the issue and even get performance benefits from off-screen surfaces and not to disable it... Well one may be wrong, This could be done months ago anyway. The pre-surface driver didn't support image cache either and performance of surface-enabled cache-less driver regressed compared to it. Therefore the root cause is somewhere else and closing this bug is the best way to make the it backfire on us later. Reopening and un-marking as dupe based on reasons stated above. |
