SUMMARY

On very rare occasions I see those artifacts in the Firefox browser, but only around the address bar and the tabs.
If I interact with the system, the artifacts are immediately gone.

I am not sure whether this is a KWin issue, a graphics driver issue, a GTK issue or has its roots somewhere else.
However, I only have experienced it under KDE so far for quiet some time now, ie several months.

Does this issue happen with other clients?

I have _only_ observed it with the Firefox so far.

Can no longer observe this weird bug. :)
