<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">You can use QMetaObject::invokeMethod with Qt::QueuedConnection.</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">Oh, I thought QueuedConnection needed to get to the event loop to execute the slot method, but I just noticed it's the event loop <strong>of the receiver object</strong>, so it would be fine. I'll change that.</p></div></div><br /><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D3132#inline-12178" rel="noreferrer">View Inline</a><span style="color: #4b4d51; font-weight: bold;">graesslin</span> wrote in <span style="color: #4b4d51; font-weight: bold;">x11_platform.cpp:229-232</span></div>
<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">I think you can merge the PostFrame with PostInit. So that the init test also does the freeze testing. That would also solve the conceptual problem I pointed out above.</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">Do you prefer to merge PostInit with PostFrame or with PostLastGuardedFrame? The difference would be that if it's merged with PostFrame and a user sets KWIN_MAX_FRAMES_TESTED to 0 (so no freeze detection is done when painting frames) then the detection thread and timer wouldn't be deleted and if it's merged with PostLastGuardedFrame, then a new thread and timer will be created for the frame drawing. I would merge it with PostFrame, since it requires a user who probably knows what he's doing to interact and is more optimized for 99.9999% of cases, and still an idle thread and stopped timer shouldn't consume any resources in the rare case a user sets that, but I ask just in case.</p></div></div></div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D3132" rel="noreferrer">https://phabricator.kde.org/D3132</a></div></div><br /><div><strong>EMAIL PREFERENCES</strong><div><a href="https://phabricator.kde.org/settings/panel/emailpreferences/" rel="noreferrer">https://phabricator.kde.org/settings/panel/emailpreferences/</a></div></div><br /><div><strong>To: </strong>antlarr, KWin, Plasma, davidedmundson<br /><strong>Cc: </strong>luebking, graesslin, kwin, plasma-devel, davidedmundson, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas<br /></div>
