[Bug 1122227] New: Plasma + openGL compositing = unusable graphical glitches
http://bugzilla.opensuse.org/show_bug.cgi?id=1122227 Bug ID: 1122227 Summary: Plasma + openGL compositing = unusable graphical glitches Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Major Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: sb56637@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hi, somewhere during the Plasma 5.14 and/or KDE Frameworks 5.53 development cycle, the openGL rendering backend for Plasma has become completely unusable on both of my laptops with regular Intel graphics due to the extreme graphical glitches. One runs Leap 15.0 with the latest Plasma and KDE Frameworks repos on top, whereas the other runs straight Tumbleweed, and they both recently starting having this issue, which is why I suspect something is wrong with Plasma and not the Intel Xorg driver. I'm attaching hwinfo for the one running Tumbleweed, but it's just a basic reliable Thinkpad T530 with Intel graphics. I'm also attaching a video of the graphical glitches. -- You are receiving this mail because: You are on the CC list for the bug.

Try uninstalling xf86-video-intel (to use the modesetting driver instead) and see if it helps... -- You are receiving this mail because: You are on the CC list for the bug.

That does appear to be the same. Sorry for the duplicate, I searched but didn't find anything. The X modesetting driver does indeed fix the problem. I just can't figure out why this bug isn't a much bigger deal with all sorts of reports, as it seems like such a common hardware/driver/desktop combination. -- You are receiving this mail because: You are on the CC list for the bug.
