While porting OpenJFX to devices with an electronic paper display, I
resolved three issues in the graphics module that I thought I should
pass along. The following merge request on GitLab lists the issues and
my minor changes. See the Commits and Changes tabs in the middle of the
page for details.
WIP: Patches to OpenJFX
Did I understand the code correctly? I would appreciate any feedback.
As a brief summary, the first issue, "QuantumRenderer modifies buffer in
use by JavaFX Application Thread," may be of general interest because it
occurs on the Monocle Headless and VNC platforms.
The second issue, "zForce touchscreen input device fails when closed and
immediately reopened," might affect only my platform, or maybe just the
older Linux kernel and device driver I'm forced to use, but I couldn't
find a good workaround without duplicating the entire LinuxInputDevice
The third issue, "Get two bytes for the Linux input event type, not
four," doesn't seem to cause any problems, but may still be worth fixing.
