Spurious display of frame-time statistics on some applications

Since I cannot precisely tell what upgrade (possibly nvidia-drivers from 340 to 470 or mesa 20 to 22 or even xorg-server 1.20 to 21) or following the first time I ran glxgears after upgrading ? :
I (not systematically though) can see, superposed on the upper left corner of the window of applications such as *vlc* or *chromium*, some report very similar to the one I would get running *glxgears* as one can see below on some screen capture of vlc upper-left window corner : Is this a bug ? a misconfiguration problem ? a feature ? Whatever : How can I just get rid of this ? ---------- **EDIT 1 :** Would that be the *Graphics API Visual Indicator * ?
I'd be surprised since its display is not systematic and I made sure the __GL_SHOW_GRAPHICS_OSD environment variable is not set. ---------- BTW : Running a KDE-Plasma desktop, I know it offers the possibility to display informations regarding the frame rate but I do not think this very question related since this option is not set and the display of this information is radically different.
