<div style="font-family: 'verdana'; font-size: 12px; color: #000;">Hi Lukasz,</div>
<div style="font-family: 'verdana'; font-size: 12px; color: #000;"> </div>
<div style="font-family: 'verdana'; font-size: 12px; color: #000;">I can reproduce both bugs with the newest version from the sandbox repository.</div>
<div style="font-family: 'verdana'; font-size: 12px; color: #000;">I created a reproducer, both bugs are very simple to reproduce there</div>
<ul>
<li style="font-family: 'verdana'; font-size: 12px; color: #000000;">The fullscreen bug: Just press ALT+ENTER, and the window tries to get into fullscreen, fails and the exception is printed. <br>Interestingly, this seems to be a new feature from Direct3D 12? Because before, ALT+ENTER did nothing for me <br>(I reimplemented that into an application, thats where I found this problem initially, but found out that this works even without handling ALT+ENTER since Direct3D 12) </li>
<li style="font-family: 'verdana'; font-size: 12px; color: #000000;">The LineChart bug: Just resize the window, the LineChart Axis Text disappears sometimes. <br>This happens for me even initally in another application. Works on the latest branch without Direct3D 12.</li>
</ul>

<p class="MsoNormal">Hi Marius,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks for checking! It is difficult to say whether this is still an issue, as that EA build is already a couple months old and I did squash some similar looking bugs since then.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We have a new one in the works, but if you don’t want to wait for it you should be able to build the most recent version out of jfx-sandbox repo, “direct3d12” branch and test this again (on that branch D3D12 builds by default so you shouldn’t have to worry about any additional flags for gradle). If the problem still persists, submitting a JBS issue with a reproducer would be helpful.</p>

</div>
</div>
<div>
<p class="MsoNormal">Hello openjfx-dev,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">we just pushed a prototype of a new JavaFX Direct3D 12 rendering pipeline</p>
<p class="MsoNormal">for Windows to a new "direct3d12" branch on jfx-sandbox. It is more than an</p>
<p class="MsoNormal">experiment branch - we intend to fully develop the D3D12 backend there.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We're not necessarily looking for contributions at this point, but if anyone</p>
<p class="MsoNormal">has early feedback about it or wants to try it by building it themselves,</p>
<p class="MsoNormal">that would be fine. We also did not test it on a wider range of hardware, so</p>
<p class="MsoNormal">your mileage may vary. While D3D12 pipeline will build by default, D3D9</p>
<p class="MsoNormal">pipeline is still the default pick at runtime. To run anything on D3D12</p>
<p class="MsoNormal">pipeline you need to force it with ex.:</p>
<p class="MsoNormal"> java -Dprism.order=d3d12 ...</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Backend supports 2D rendering (albeit with some graphical issues here and there</p>
<p class="MsoNormal">that need to be ironed out) and basic 3D rendering. Expect not everything fully</p>
<p class="MsoNormal">working yet (ex. some gradients on 2D controls are incorrect, or 3D-in-2D will</p>
<p class="MsoNormal">straight up not work) and the performance not matching D3D9 yet. Our goal is to</p>
<p class="MsoNormal">first reach feature completion and then focus on performance.</p>
<p class="MsoNormal"> </p>
