Description mlessard 2015-02-19 15:57:20 UTC
Description of problem:
With Spice, when we connect to a Windows 7 sp1 vm (32 bits) (with 4 monitors) with a resolution of 2500 * 1600, the characters are very blurry. We also experiencing freezing. 

Version-Release number of selected component (if applicable):
RHEV 3.5
Virtual machine : Windows 7 sp1 32 bits
Workstation Host OS : Windows 7 sp1 32 bits

How reproducible:
Just tested on a single RHEV environment 

Steps to Reproduce:
1. Install a Windows 7 sp1 vms (32 bits) on RHEV 3.5 with 4 monitors
2. From a Windows 7 workstation, console to the VM
3. Set the resolution of the 4 monitors to 2500 * 1600
4. Move an application between the 4 monitors

Actual results:
The characters are very blurry. 
The console session get freeze.  We need to use another computer to connect to the session to retrieve the session back. The vm is not freezed, but spice is.  

Expected results:
Characters should be clear. No freeze should happens. We tested in a lower resolution (1700 x ...) and characters are clear, and no freeze happened. 

Additional info:

Comment 2 Yvugenfi@redhat.com 2015-02-22 10:15:39 UTC
Regarding the blurry characters - are you using physical monitors with 25X16 resolutions or greater?

Best regards,
Yan.

Comment 3 mlessard 2015-03-03 13:21:03 UTC
Yan, 

Presently, they use those workstations at that resolution and it's not blurry.

Comment 5 Kirill Moizik 2015-03-04 09:43:39 UTC
Hi,
1) Please check out printscreen, is this what you call blurry ?
   if yes it caused by difference between host and guest resolution.
2) Please ellaborate on bug reproduction frequency and vm details, cpus, memory etc.
Thanks,
Kirill

Hi Kirill,

Thanks.

Comment 43 David Blechter 2016-05-10 14:12:23 UTC
Pavel,

please verify with spice qe setting of 4*(2560x1600) on windows 7 VMs

Comment 44 Pavel Grunt 2016-05-12 10:30:22 UTC
I have no problems running 4*(2560x1600) on win7 client & guest. (I used rhevm3.6)

Bug 1244869 has similar symptoms - client (virt-viewer) freezes with high resolution. That bug is fixed in rhevm3.6 client
