#### Motivation
During our graphical YaST tests we (the qe-yam team) encounter a type of graphic glitch where the screen is not properly refreshed.
Examples can be seen [here](https://openqa.suse.de/tests/10436703#step/iscsi_client/57) and [here](https://openqa.suse.de/tests/9680782#step/yast2_control_center/96)
This behavior is sporadic but widespread enough that it has forced qe-yam to apply [workarounds](https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/15889) to a number of our tests.
Because the conditions allowing the workarounds are not always consistent, we have interest in the root of the issue getting resolved.
Our [latest bug entry](https://bugzilla.suse.com/show_bug.cgi?id=1204176) on the matter has been tagged as WONTFIX because we (qe-yam and the YaST developers) have not found a way to reproduce this glitch outside of the openQA environment.
latest: https://openqa.suse.de/tests/10499467#step/yast2_lan_restart_vlan/19 (glitch does not happen on yast2_control_center on last build but can be seen elsewhere)
last good: https://openqa.suse.de/tests/5900202#step/yast2_control_center/94
### Scope
aarch64, s390x, x86_64 on SLE 15-SP5 (issue is not exclusive on qemu)
#### Acceptance criteria
* **AC1:** The graphic glitch does not appear anymore in tests
### Suggestions
* It looks like window decorations are missing from the dialog
* The emulated graphics adapter might be causing problems with the window manager
* Research what options could be used with the graphics emulation in qemu
* Identify the underlying parameter(s) in the openQA environment that can cause this graphical glitch.
* Find a last good? We couldn't find one easily?
* could be a VNC-related issue? Missing borders may occur there
