Doc Text:	Zooming in and out on a window in virt-viewer/remote-viewer would sometimes cause the guest display to be resized rather than simply scaling the local display. After this change, the guest display will never be resized in response to zooming in or out in the client (view > zoom > zoom in / zoom out). It will simply scale the display up or down.

Description Vimal Patel 2013-09-03 19:16:12 UTC

Description of problem:
The behavior of zooming out of a RHEL guest is inconsistent.  Most of the time the way zooming out behaves is: The resolution of the guest stays the same, and the geometry or window size of the remote-viewer window decreases.

However, occasionally (1/4 times?) when zooming out the guest's resolution changes and the window size decreses.  This seems to happen more when trying to zoom out multiple times in a row.

An automated test caught this issue, it can be reproduced manually and it look like the following:

1024x768 [Zoom In] ->
1024x768 [Zoom In] ->
1024x769 (Guest Resolution Changed?) [Zoom In] ->
1024x768 (Guest Resolution Changed again, back to original?) [Zoom In] ->
1023x768 [Changed Again?]

Comment 2 tingting zheng 2013-10-23 08:27:13 UTC

I can reproduce this issue with:
virt-viewer-0.5.6-8.el6.x86_64

The original resolution of the guest is 1280x768,when zoom out several times,it will changed.

1280x768 [Zoom out] ->
1280x768 [Zoom out] ->
1280x769 [Zoom out] -> Resolution changed.
1280x768 [Zoom out] -> Resolution back to original.

fixed upstream in 895ef8029e794e7b74a45f27c7c741d1332bc02b

Note: the previously mentioned patch had problems and was reverted, the proper upstream patch is 8fa9423bd873f2283be7b1e1e2fc80ffe8785155

Comment 8 tingting zheng 2014-06-06 07:07:57 UTC

I can reproduce this bug with:
virt-viewer-0.5.6-8.el6.x86_64

Tested pass with:
virt-viewer-0.6.0-5.el6.x86_64

Set the original resolution of the guest as 1280x768,when zoom out several times,it will not change.Also tried some other resolutions,when zoom out,the resolution will not change,so move the bug to VERIFIED.
