Hi, I’m using an old machine with an Intel HD Graphics 4000 graphics card. In any application, if I use a black theme, I see black dots, and if I use a white theme, I see white dots. I have observed this on other laptops with the same graphics card. If I switch to my second graphics card, nvidia geforce gt 740m, the problem is solved, but I want to use the intel graphics card and I think this is not a solution because I have another laptop with only intel graphics card. I usually see this black dot problem more in programs written in QT. I will try to add a video. The video has a detailed demonstration of the error. Note : I am currently using arch linux, but this error appears in all linux distributions that use kde without exception. I encountered this error in Kubuntu, Debian, KDE Neon, Arch, Fedora SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.2.6 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.1

Moving to KWin as it is related to all applications and graphical glitching.
It looks to me like a graphics driver bug
Hi - do these artifacts follow the cursor at all, or is their appearance/location changed when passed over by the cursor? In the System Settings > Display & Monitor section, are you using a display scaling percentage other than 100%? Are you using a color profile on your display? Thanks!

They do not react to the presence and movement of the cursor. 2) I use 100% as the display scaling percentage. 3) I do not use a special color profile. I also encounter this problem after installing any Linux distribution for the first time, even if I do not customize it and try to use it out of the box. Finally, I apologize for my bad English

Does the issue show up if you boot from a Live USB, without installing? And does the issue show up if you boot from a Live USB using a desktop environment other than KDE Plasma?

When I tried a distribution that uses GNOME via live USB, I did not encounter this problem in the system interface and the GTK applications in it, but I encountered black dots in Firefox again.
