[plasmashell] [Bug 444015] plasmashell crashes at showing window thumbnails
https://bugs.kde.org/show_bug.cgi?id=444015 --- Comment #7 from Nate Graham --- Git commit 80928f4344af159f58e61225a02ea7a874cb5493 by Nate Graham, on behalf of Fushan Wen. Committed on 20/10/2021 at 16:56. Pushed by ngraham into branch 'master'. taskmanager: Ensure tooltips are really disabled when "Show tooltips" is unchecked Before frameworks/plasma-framework!358, if enabled is not set (default true), when the tooltip is disabled in the settings, plasmashell will still crash at showing window thumbnails, which means the content in the tooltip is just not visible, but the relevant code is still executed. This ensures tooltips are really disabled when "Show tooltips" is not checked, which is beneficial for people who want to extend the battery life or avoid the unresponsiveness caused by tooltips.

https://bugs.kde.org/show_bug.cgi?id=444015 --- Comment #6 from David Hurka --- Created attachment 142630 --> https://bugs.kde.org/attachment.cgi?id=142630=edit New crash information added by DrKonqi plasmashell (5.23.80) using Qt 5.15.3 - What I was doing when the application crashed: Move mouse cursor on the task manager. - Custom settings of the application: I have the panel on the top, otherwise it is as usual. When the crash first appeared, I had two windows with the same title (one with <2> appended), and a fullscreen window. This crash appeared immediately after installing updates and logging in again. The Alt+Tab task switcher (which also uses thumbnail images) works correctly. -- Backtrace (Reduced): #3 0x7fa598fd17c4 in Plasma::WindowThumbnail::updatePaintNode(QSGNode*, QQuickItem::UpdatePaintNodeData*) (this=0x55ba251e92c0, oldNode=, updatePaintNodeData=) at ./src/declarativeimports/core/windowthumbnail.cpp:327 #4 0x7fa606c82380 in QQuickWindowPrivate::updateDirtyNode(QQuickItem*) (this=0x55ba23b02970, item=0x55ba251e92c0) at items/qquickwindow.cpp:3872 #5 0x7fa606c82c3b in QQuickWindowPrivate::updateDirtyNodes() (this=this@entry=0x55ba23b02970) at items/qquickwindow.cpp:3617 #6 0x7fa606c84330 in QQuickWindowPrivate::syncSceneGraph() (this=this@entry=0x55ba23b02970) at items/qquickwindow.cpp:524 #7 0x7fa606c21e97 in QSGRenderThread::sync(bool, bool) (this=this@entry=0x55ba24985240, inExpose=inExpose@entry=false, inGrab=inGrab@entry=false) at scenegraph/qsgthreadedrenderloop.cpp:647 -- You are receiving this mail because: You are watching all bug changes.

Committed on 19/10/2021 at 11:44. Pushed by ngraham into branch 'master'. Fix crash in WindowThumbnail::updatePaintNode() Recently, the WindowThumbnail was changed so it properly discards the texture provider in the releaseResources() function. But it appears like there's a case where the releaseResources() function can be called in the windowToTexture() function, which will result in use after free bugs. Based on af5a855da42c3ada2f0e802c68ad8f7c0e73b38e, it looks like the WindowThumbnail item didn't use QQuickItem::releaseResources() to properly release its graphics resources. It was checking whether the texture node still has a texture. If there's no texture, it means that the texture got discarded and it needs to be re-created; otherwise it is okay to re-use the old texture. With QQuickItem::releaseResources(), we don't need that workaround anymore since QtQuick will call the releaseResources() function whenever it wants the WindowThumbnail to discard graphics resources.
