#### 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. 

 ### 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
