[kwin] [Bug 407612] [Wayland] On Plasma 5.16 beta, with any Window Decoration theme other than Breeze, Kwin eats all the RAM in a few seconds and the session hangs
https://bugs.kde.org/show_bug.cgi?id=407612 --- Comment #28 from Vlad Zagorodniy --- Git commit f5b66a583de4ddfc6982d5bc54a307476077fc0f by Vlad Zagorodniy. Committed on 01/07/2019 at 19:04. Pushed by vladz into branch 'master'. [plugins/qpa] Implement native offscreen surface Summary: Depending on whether the underlying platform supports offscreen surfaces, QOffscreenSurface may create an invisible QWindow. In our case that's the case, for each offscreen surface a native window is created. This may lead to some funky results related to window decorations, see bug 407612. There are several ways to implement offscreen surfaces - either use pbuffers or utilize a surfaceless context extension. For the sake of simplicity this change sticks with pbuffers, but it's a good idea to support both methods.

Committed on 28/06/2019 at 22:24. Pushed by vladz into branch 'Plasma/5.16'. Decorate only toplevel internal clients Summary: Unfortunately Aurorae decoration engine creates several internal clients per each decoration. One of those clients represents QOffscreenSurface, which is not a toplevel. Given that no QWindow object will be found for such clients, m_internalWindowFlags contains undefined value. Luckily, QOffscreenSurface sets FramelessWindowHint flag, but because InternalClient is not able to find matching QWindow object, cached QWindow flags won't have that hint set. Thus InternalClient will attempt to decorate QOffscreenSurface. A new Aurorae decoration will be created, which means a new QOffscreenSurface will be created, which means a new Aurorae decoration will be created, and so on. This change restricts subset of internal clients that can be decorated. Only clients with valid m_internalWindow can be decorated. If m_internalWindow isn't null, then m_internalWindowFlags is guaranteed to be valid as well.

Simply running "kwin_wayland --exit-with-session termite" from a TTY starts a KWin session, but eats the whole RAM in a matter of seconds (I picked termite as an application because it has native Wayland support and allows me to see the RAM usage, but Konsole running through XWayland gave the same result).

On processes card, it's visible that kwin-walaynd is eating RAM and CPU but I didn't manage to do a second screenshot. RAM increase was too high and too quick. You can also see the lack of proper titlebar (Aurorae theme Breezmite) which is causing the issue with kwin-wayalnd. Again, when I switched to Breeze aurorae theme, there was no memory leak on wayaland session. -- You are receiving this mail because: You are watching all bug changes.

At first, I thought it's about window theme so I switched from kvantum to Breeze, no effect, heavy memory leak still occurred on kwin-wayland. I noticed that the Aurorae theme (window decoration theme) was not properly displayed I switched from Breezmite to Breeze and... it fixed the issue, memory leak stopped. The issue happened on Intel proprietary drivers, didn't dare to test Nvidia in such case. The memory leak was too severely crippling the system so it was even hard to take any screenshot. In a matter of seconds, memory and CPU were used and hang.

After going back to breeze the performance recovers but the memory won't get freed. Even setting everything back to breeze won't recover the lost memory. Somehow going from affected decoration to affected decoration to breeze decoration will recover some lost memory (in my case plastik -> adapta -> breeze). -- You are receiving this mail because: You are watching all bug changes.

Do you mean changing from one affected theme to another or from a theme that comes with a leak back to Breeze or some unaffected theme?
