If you're able to downgrade Qt, could you please try to reproduce the bug with Qt 5.11.X? I still have 5.11 packages in my /var/cache/pacman/pkg/ folder, which one should I reinstall ? I don't feel like reinstalling ALL 5.11 packages... Oh, you're using Arch. Nevermind then, downgrading packages on Arch is PITA. @Vlad, what were you thinking could be the cause that you wanted to test? @tromzy as well as trying different window decos, see if changing the qstyle theme makes a difference. I started noticing this issue after upgrading to Qt 5.12. Though on X11, it's occasional. Changing the Qt style makes a difference, but other problems occur too. The black rectangle problem seems to happen only with Kvantum Qt style ; other styles like Fusion or Breeze have their own set of glitches, but not the "rectangle for shadow" one. After updating Qt to 5.12.1, I no longer able to reproduce it. I am on QT 5.12.1 too and the bug still occurs. > other styles like Fusion or Breeze have their own set of glitches
Are they still present?
Hmm, I just changed from Kvantum to Breeze style ; the glitches are still present with Breeze ; but then I switched back from Breeze to Kvantum and... Problem solved ! It seems to draw the shadow correctly (although other problems remain, like the inability to close the context window, but that is probzbly another issue). (In reply to tromzy from comment #11) > the glitches are still present with Breeze What glitches exactly? Created attachment 117923 [details]

Breeze Window decoration 2
See the 2 screenshots I provided : on "Breeze window decoration 1", I just made a right click on the title bar : the entries are blue-ish. On "Breeze window decoration 2", this is after I hovered every entry : they got even more blue. Hmm, that glitch looks unrelated to this report. Anyway, I'm marking it as WORKSFORME. If you're still able to reproduce this bug, please file a bug report downstream (kvantum). If it turns out that's a problem in KWin (very unlikely), then please reopen this bug report. |
