[kwin] [Bug 406319] Hangs/freezes when drag windows to top, right or left edges of the screen
https://bugs.kde.org/show_bug.cgi?id=406319 --- Comment #8 from Vladislav Rubtsov --- Any updates on this bug's status? I suffer from this bug too and I originally opened Bug 406307 with similar report (which was marked as duplicate, though posted earlier). Setting Compositor Rendering backend to "Xrender" as others suggested doesn't fully fix the issue on my end. It just makes freezes occur somewhat less. I would say with "OpenGL" window dragging animations exhibit freezes 90% of the times (was far less frequent before the 5.15.4 update), and with "Xrender" it's only 10-15%, which is of course a lot better, but the bug is still there.

https://bugs.kde.org/show_bug.cgi?id=406319 biblicabee...@gmail.com changed: What|Removed |Added CC||biblicabee...@gmail.com --- Comment #7 from biblicabee...@gmail.com --- I found I was able to cause this hang reliably, and that it could be fixed by setting the compositor to xrender, both OpenGL 2.0 and 3.1 have this bug. The trigger I had was alt-tabbing, and it seems to only trigger for some programs. It was very reliably triggered when alt-tabbing into and out of Terminator, and seems 100% reliable going from Chrome into Terminator. (Thought: could this be GTK related?) Potentially relevant settings?: compositor - animation speed one step above instant compositor - full screen repaints compositor - keep window thumbnails only for shown windows task switcher - "show selected window" is ticked task switcher - visualization is "Compact" software: KDE Neon, up to date. hardware (separate systems, same physical hard dive): Dell 5491 laptop, nvidia mx130 - Maxwell - very similar to original report. Thinkpad w530 laptop, nvidia k1000m - Kepler - architectural generation behind original report. I've tested these drivers from the third party drivers PPA for nvidia (ppa:graphics-drivers/ppa): 390 (available without ppa): exhibits bug 418: exhibits bug (This is my first post, please let me know if I need to include anything/read through some guidelines...) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406319 --- Comment #6 from Thanh --- Update: - On my laptop (OpenGL renderer: NVIDIA), I cliked on System Settings > Display and Monitor > Compositor, change Rendering backend to "XRender", Log out and Log in again, the hang/freeze doesn't occur anymore. - Then, I tried changing Rendering backend to OpenGL 2.0 or OpenGL 3.1, then Log out and Log in, the hang/freeze happened again. Is it related to "Compositor Settings for Desktop Effects", "OpenGL" and "NVIDIA"? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=406319 --- Comment #5 from Markus Heß --- Update: The issue seems to be related with the screen configuration. On my laptop, a second screen is connected. When I unplug the screen, the freeze doesn't occur anymore. After reconnecting the screen cable, the freezes happen again. Disabling the screen in the system settings also helped. Here, even if I re-enable the screen, the issue does not happen again. -- You are receiving this mail because: You are watching all bug changes.
