Created attachment 167381 [details] Screenshot while alt tab didn't work SUMMARY The tabbox rendering seems a bit wrong on during zypper update. I may try to reproduce this rendering error on the next zypper update STEPS TO REPRODUCE 1. Open konsole 2. sudo zypper update 3. Alt tab to see the tabbox OBSERVED RESULT These strange these strange dotted white circles. EXPECTED RESULT I do not know whether this effect is intended SOFTWARE/OS VERSIONS Information for package plasma6-mobile: ---------------------------------------t Repository : openSUSE-Tumbleweed-Oss Name : plasma6-mobile Version : 6.0.2-1.1 Arch : x86_64 Vendor : openSUSE Installed Size : 5.8 MiB Installed : Yes Status : up-to-date Source package : plasma6-mobile-6.0.2-1.1.src Upstream URL : https://www.kde.org/ Summary : Plasma shell for mobile devices Description : Plasma shell for mobile devices.

Well that doesn't seem intended!
(In reply to Nate Graham from comment #3) > Well that doesn't seem intended! You can reproduce the bug with echo "...................................................................................." plus alt+tab
This looks like it could just be an artifact from texture filtering. When the source texture is much bigger than the target, sometimes weird patterns can emerge from which pixels are chosen for filtering

The locations seem to be same as here but the render error is different https://gitlab.freedesktop.org/drm/amd/-/issues/3306#note_2348669
That pattern is from the buffer data layout, but it's likely just a coincidence.

We could maybe get mipmapping for the textures to reduce this effect, but it would come at a potentially big performance penalty in an already pretty heavy effect, so I think it's best to just leave it like this.
