## #### 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 ## Problem * *H1* could be the qemu video adapter * *REJECT* *H1-1* could be the specific choice of qemu video adapter * *E1-1* Try out the reproducing openQA test with different qemu video adapters -> *O1-1-1* different video adapters reproduced the same issue * *H1-2* maybe can not be reproduced with using special qemu video adapter settings * *H2* only happens in older SLE versions * *E2-1* Run the equivalent openQA test on current Tumbleweed * *ACCEPT* *H3* can only be reproduced in openQA * E3-1* try to reproduce manually -> no one could reproduce manually ## ### 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 ## Further details [Link to latest](https://openqa.suse.de/tests/latest?arch=x86_64&distri=sle&flavor=Online&machine=64bit&test=yast2_gui&version=15-SP5)
