Hi: On 9 Feb my f38 system was updated from kwin 5.27.4 to 5.27.10 and
I started seeing popups and minor hesitations linked to graphics resets.
I haven't found a reliable way to reproduce them. Today I downgraded
kwin-x11 etc back to 5.27.4, and opening Firefox still gave the popup.
nVidia 470xx from rpmfusion, MythTV master.
Google finds lots of years-old hits, including kde bug 385324, and a
suggestion to retoggle kwin with Alt/Shift/f12, but this behaviour was
new to me. Any comments or suggestions?
TIA
John P
