Application: plasmashell (5.27.5) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 6.1.0-17-amd64 x86_64 Windowing System: Wayland Distribution: Debian GNU/Linux 12 (bookworm) DrKonqi: 5.27.5 [CoredumpBackend] -- Information about the crash: When moving a widget with a transparent background to the second screen, the desktop goes black, the panel flashes, and then Plasma restarts. After that the widget disappears. Initially three Quick Starts were successfully moved, then all subsequent move attempts (Quick Start and Disk Activity) failed. (All these widgets have a transparent background) Movement behaves fine after adjusting their background to default. 将透明背景的小部件移动到第二屏幕时，桌面黑屏，面板闪烁，随后Plasma重启。之后小部件消失。 一开始成功移动了三个“快速启动”，之后所有移动尝试（“快速启动”与“磁盘活动”）都失败。（所有的这些小部件都是背景透明的） 将它们的背景调整为默认后移动行为正常。 The crash can be reproduced every time. -- Backtrace (Reduced): #6 0x00007f875c79e1ff in QSGBatchRenderer::Renderer::uploadBatch(QSGBatchRenderer::Batch*) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007f875c7b0526 in QSGBatchRenderer::Renderer::render() () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #8 0x00007f875c797f00 in QSGRenderer::renderScene(QSGBindable const&) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #9 0x00007f875c7983b3 in QSGRenderer::renderScene(unsigned int) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #10 0x00007f875c7fb663 in QSGDefaultRenderContext::renderNextFrame(QSGRenderer*, unsigned int) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 The reporter indicates this bug may be a duplicate of or related to bug 479001.

Created attachment 178415 [details] New crash information added by DrKonqi plasmashell (5.27.5) using Qt 5.15.8 When moving the "Digital Clock" widget (transparent background) from the secondary display, to the primary display (configuration is three monitors with primary in center, secondary to the left, and tertiary to the right of primary). The plan was to move and resize the widget so I dragged it over to the and it appeared properly on the primary display and I immediately went to resize the widget and during the resize, (so 1 click and hold on the bottom right corner, drag toward the bottom right corner of display) before I released the click/drag, the widget had disappeared and approximately 1-3 seconds later all displays went black for a moment, then returned with only the gui's of whatever I applications I had open (Konsole, and a system settings interface), followed by wallpapers and taskbar after (I assume) KDE restarted. -- Backtrace (Reduced): #4 0x00007f68d7daa5d7 in QSGBatchRenderer::Renderer::renderMergedBatch(QSGBatchRenderer::Batch const*) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #5 0x00007f68d7dafc7b in QSGBatchRenderer::Renderer::renderBatches() () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #6 0x00007f68d7db05b6 in QSGBatchRenderer::Renderer::render() () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007f68d7d97f00 in QSGRenderer::renderScene(QSGBindable const&) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #8 0x00007f68d7d983b3 in QSGRenderer::renderScene(unsigned int) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5
Following up to my first report of this bug. It is not caused (in my case) by moving the widget to a different display in and of itself. The crash/bug was duplicated by resizing the same widget (transparent background) beyond a certain size immediately following the move to a different display. I am not sure whether the move is necessary or not, but the resize is. During the resize, the first line (the clock with a larger font size) disappeared first but the bottom line with smaller text did not. Continuing to drag the corner and increase the size caused both lines to disappear and provided the same results as my previous report. Hope this helps :)

I added more information in a comment to my first report confirming the cause of what I experienced. Can confirm it is also related to resizing the widget in both of my reports. -- Backtrace (Reduced): #4 0x00007fb35cbaa5d7 in QSGBatchRenderer::Renderer::renderMergedBatch(QSGBatchRenderer::Batch const*) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #5 0x00007fb35cbafc7b in QSGBatchRenderer::Renderer::renderBatches() () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #6 0x00007fb35cbb05b6 in QSGBatchRenderer::Renderer::render() () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007fb35cb97f00 in QSGRenderer::renderScene(QSGBindable const&) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5 #8 0x00007fb35cb983b3 in QSGRenderer::renderScene(unsigned int) () from /lib/x86_64-linux-gnu/libQt5Quick.so.5
