Can reproduce this bug on my ThinkPad T480s laptop, wayland session, Arch Linux.

Curiously, this is NOT present on my AMD/Nvidia main pc, only my intel/intel laptop. Not sure what's going on there, but for interest's/debugging's sake my pc without the issue is:

I can also reproduce. It only happens sometimes but not always.

Comment 10 Robert 2024-06-16 17:05:49 UTC 
I can also reproduce, a fresh session works fine, however, when a window is maximized and then closed, the bug appears. The tooltips for panel elements are also defective with cut off corners where some of them don't have rounding.

Restore proper devicepixelratio when extracting from cache

like in base Svg, also in FrameSvg restore the proper devicepixelratio
when getting the image from the cache, as KImageCache doesn't save or
restore the information about it.

This fixes blur region mask sometimes wrong behind floating panels

Is it possible to backport this fix to Framework 6.3.x so that we don't have to wait another month?

Yup, same question. Things like that completely ruined user experience. From developer and logic perspective it's almost nothing but if you have to look at it everyday it's... I already can't stand with only 1 day

So, yes, please guys release some kind of fix very soon :) or how we can temporary fix it if it possible before release fix if it take long time.
Comment 19 nlearned 2024-06-19 16:22:00 UTC 
I just compiled the latest git master and it seems to work fine. A backport would be nice though.
Comment 20 Owabs Zhar 2024-06-19 22:18:56 UTC 
I second the motion for a backport.
Comment 21 Felix Zhu 2024-06-20 11:11:51 UTC 
I'd also like a backport
Comment 22 Nate Graham 2024-06-20 12:37:51 UTC 
It looks like all the Frameworks packagers are on vacation right now, so unfortunately a new Frameworks release from KDE is not likely. I've emailed distros about this and asked them to backport it themselves, so the good distros should be shipping the a backport soon.

Thanks Nate, Arch has already backported the fix to stable and I just installed the latest KSvg and Plasma 6.1 and can confirm that all artifacts are gone, keep up the good work.
Comment 26 Nate Graham 2024-06-20 18:20:43 UTC 
In this case the good work was done by Marco who fixed it, and Jonathan who made a release of KSvg while on vacation! :O
Comment 27 Shakeel 2024-06-20 18:34:12 UTC 
Thanks Nate, Marco and Jonathan. Really appreciate your efforts on fixing this issue.
I can confirm the fix is now available in Arch repos and working great. 
Kudos to all...
