<p>I was testing this on slightly different device then i915, and based on quick debugging, it seems TEST_ONLY commit is failing correctly all the time but when trying to reset the lastState it goes into infinite loop.</p>
<p>I did more investigation and for some reason last state is set to incorrect mode, which starts recursion.. I am yet to figure out why this happens, is it DRM lying to us or something I am not quite sure. If I can't figure this out by this week, let's merge this I guess.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D24112">https://phabricator.kde.org/D24112</a></div></div><br /><div><strong>To: </strong>romangg, KWin<br /><strong>Cc: </strong>bshah, zzag, apol, kwin, LeGast00n, The-Feren-OS-Dev, sbergeron, jraleigh, fbampaloukas, GB_2, mkulinski, ragreen, jackyalcine, iodelay, crozbo, bwowk, ZrenBot, ngraham, alexeymin, himcesjf, lesliezhai, ali-mohamed, hardening, romangg, jensreuterberg, abetts, sebas, mart<br /></div>
