SUMMARY If I put any non-Qt/Kde window crossing two screens and move the mouse over it, the cursor is hidden when it crosses the screen border until it reaches that window border. It does not reappears if I simply move back to the old screen. The same does not happen with Qt apps. Mouse even like click, does still work (but it does not make the mouse cursor back). 1. configure side-by-side screen 2. open xterm 3. put the xterm screen over the border between the two screens 4. move the mouse cursor over the xterm window and across the screen border OBSERVED RESULT 5. mouse cursor is hidden. EXPECTED RESULT 5. mouse cursor should be still there as usual. SOFTWARE/OS VERSIONS Linux/KDE Plasma: OpenSUSE Tumbleweed 20220917 KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION
I can't reproduce it.
Created attachment 152509 [details] Photo of a hidden cursor I activated the "Follow mouse effect" to show that the mouse cursor was there and externally took a picture. I tried to record the screen or that a screenshot but the mouse was there. My multiscreen is not a simple side-by-side. The left monitor is rotated, with extra border over and under the right monitor. There is no screen overlap.
Can you post the output of `qdbus org.kde.KWin /KWin supportInformation`?

Hmm, I see nothing "weird" about your setup. A shot in the dark: - can you run kwin with KWIN_DRM_SW_ROTATIONS_ONLY=1 environment variable set? e.g. you could put it in /etc/environment and reboot the computer - if the issue is still reproducible, can you try setting KWIN_FORCE_SW_CURSOR=1 too?

With KWIN_DRM_SW_ROTATIONS_ONLY=1, the issue is still there With KWIN_FORCE_SW_CURSOR=1, it worked as expected. I tested the KWIN_FORCE_SW_CURSOR keeping KWIN_DRM_SW_ROTATIONS_ONLY set. Is it worth it to test it without KWIN_DRM_SW_ROTATIONS_ONLY? The software cursor now draws a darker region over the konsole black (with a little bit transparent) background for a second while moving when konsole when the window under it is mostly white. I don't know how software cursors works today but in the old times, we used to copy the region where the cursor would appear, draw, before drawing the next cursor position, erase it pasting the copied region. It looks like kwin copied konsole region (or asked konsole to do it) without considering the transparency effect, just like the spectacle ignores that same effect while taking a screen shot.
